Ubuntu Server fails #2

phsimons · 2020-11-28T10:43:35Z

Hello,
I am very interested in trying this.
I am trying ubuntu-20.04.1-live-server-arm64.iso and would like to perform a install. so I also created a DMG. But it does not seems to launch the installer ... do you have an idea what I am doing wrong ?

I use the following parameters
./vftool -k /Users/simonph/Desktop/Ubuntu/UbuntuServer/vmlinuz -i /Users/simonph/Desktop/Ubuntu/UbuntuServer/initrd -d /Users/simonph/Desktop/Ubuntu/VM.dmg -c /Users/simonph/Desktop/Ubuntu/UbuntuServer/ubuntu-20.04.1-live-server-arm64.iso

And here is the console

sylvainfilteau · 2020-11-28T13:25:58Z

How did you obtain the kernel and initrd files ? I'm trying to find this since yesterday 😅

phsimons · 2020-11-28T16:43:53Z

You can find vmlinuz and initrd inside the iso image. (I used Keka to mount it). For the vmlinuz, you have to copy it, then rename it as .gz and extract.

sylvainfilteau · 2020-11-28T18:15:50Z

Did you do anything to the initrd file ?

phsimons · 2020-11-28T18:20:16Z

no

sylvainfilteau · 2020-11-28T19:27:43Z

if you type exit at the prompt, it may give you some insight at what is going on.

phsimons · 2020-11-29T08:29:13Z

Probably missing some -a but which ones

sylvainfilteau · 2020-11-29T13:35:31Z

try with -a "console=hvc0 root=/dev/vda1" I think it needs other arguments to work well because right now the text is all messed up. But thats progress

phsimons · 2020-11-29T13:49:42Z

I have tried that , but nothing appears on the /dev/ttys now

rossbachp · 2020-11-29T15:49:47Z

I got this after connect with screen /dev/ttys002 waiting message:

How I am create the disc /Users/peter/VM/VM-Ubuntu.dmg ?

rossbachp · 2020-11-29T16:13:59Z

Create an empty disc with the MacOS disk utility. The virtual machine failed to start!

evansm7 · 2020-11-29T16:23:22Z

Hi all (I'm late to the thread, real life intervened) :) I've just tried an ubuntu-server ISO again, and can re-create. Two things to note:

The default RAM size (512MB) is too low for the ubuntu initrd -- passing -m 2048 solves the (initrd) prompt issue that @phsimons reported.
The ubuntu installer is unusable as @xiaolait and @sylvainfilteau note. (Even hitting ^T for simple mode, it's getting random keypress inputs.)

Notes on installers:

Ubuntu-server boots, but the terminal is unusable.
Debian install kernel/initrd on the debian-10.6.0-arm64-netinst.iso doesn't appear to have virtio drivers, so is a no-go. I installed Debian using debootstrap (see below).
Fedora-33 boots, but then seems to crash (it immediately terminates/init halts the system).
openSUSE-Tumbleweed-NET-aarch64-Current.iso (as of 28Nov20) installer boots nicely, is colourful and is usable, except has minor terminal issues: I keep having to hit tab/return to get the package download bargraphs to update.

However.... I don't believe running the installers is as easy as it sounds at this stage: once the packages are installed to your disc.img, then you'll need to fish out a kernel/initrd from the installed image, back to macOS, to boot it. (The initrd and likely the kernel will be different to those the installer uses.)

For this reason, enduring a chicken & egg situation and solving with another Linux box is IMO the easiest route currently. For example, installing Ubuntu or Debian using debootstrap, something like:

Create a disc image, partitions, rootfs
Mount root on say /mnt
debootstrap --arch=arm64 --foreign stable /mnt as root
While that's cooking, build a mainline arm64 kernel (which won't need an initrd to boot debian, at least). When debootstrap is finished, the kernel/disc.img can be booted in a VM, and debootstrap --second-stage used to finish the installation (plus some manual stuff, like creating /etc/fstab, /etc/hosts, tzdata/locales). There are Debian/Ubuntu debootstrap directions on le net...

That doesn't help anyone that's desperate to use CentOS/Fedora etc. :) Anyone know if they have a debootstrap equivalent?

Finally: legend has it that there will be an EFI-related boot method in future, which may pave the way to booting ISOs (or even OVMF/edk2) directly, and that removes all of this faffing around with finding kernels/initrds. Hopefully a future macOS release will provide, here.

evansm7 · 2020-11-29T16:35:25Z

Create an empty disc with the MacOS disk utility. The virtual machine failed to start!

Oh dear -- I haven't seen this error before. The disc simply needs to be a file that exists and is of the size you want to use. For example, dd if=/dev/zero of=my_disc.img bs=1024k count=20480 makes a 20GB file of zeros.

But, see my previous message -- at this stage it is probably easiest to use Virtualization.framework/vftool with a disc image that is pre-installed elsewhere, unfortunately. Someone suitably motivated could perhaps write a script to extract kernels/initrds from a distribution install ISO, run the installer and then re-extract kernels/initrd from the installed disc, perhaps.

I'll see if I can recreate that error, though, how odd.

phsimons · 2020-11-29T19:16:07Z

Thanks for the extended explanations ...
indeed Ubuntu-server boots, but the terminal is unusable.

But at this point isn't there a way to ssh in the VM and continue the install ?

droidix · 2020-11-29T21:17:33Z

I've had good luck with the Ubuntu cloud images linked by a kind user on the MacRumors forums [1]:

Let's assume you place all of these files in a linux directory under your home directory. Prepare the kernel:

mv ubuntu-20.04-server-cloudimg-arm64-vmlinuz-generic vmlinux.gz
gunzip vmlinux.gz

The initrd (just renaming for convenience):

mv ubuntu-20.04-server-cloudimg-arm64-initrd-generic initrd

And finally, the disk image:

tar xvfz ubuntu-20.04-server-cloudimg-arm64.tar.gz
mv focal-server-cloudimg-arm64.img disk.img

With these being cloud images, I want to disable cloud-init, set the root password, generate some SSH host keys, and configure DHCP. To work on the disk image, we'll boot the virtual machine without specifying the root to the Linux command line.

vftool -k vmlinux -i initrd -d disk.img -m 1024 -a "console=hvc0"

In another terminal, use screen to attach to the tty. The VM will finish booting and drop to an (initramfs) prompt. Then run:

mkdir /mnt
mount /dev/vda /mnt
chroot /mnt

touch /etc/cloud/cloud-init.disabled

echo 'root:root' | chpasswd

ssh-keygen -f /etc/ssh/ssh_host_rsa_key -N '' -t rsa
ssh-keygen -f /etc/ssh/ssh_host_dsa_key -N '' -t dsa
ssh-keygen -f /etc/ssh/ssh_host_ed25519_key -N '' -t ed25519

cat <<EOF > /etc/netplan/01-dhcp.yaml 
network:
    renderer: networkd
    ethernets:
        enp0s1:
            dhcp4: true
    version: 2
EOF

exit
umount /dev/vda

Kill the VM with CTRL+C in the terminal you ran vftool and then run it again, but this time specifying the root to the kernel:

vftool -k vmlinux -i initrd -d disk.img -m 1024 -a "console=hvc0 root=/dev/vda"

You can now connect with screen and login to the root user with root as the password. You can also ssh into the VM if you configure your public key. Show the IP address via ip addr show | grep "inet 192"

rossbachp · 2020-11-30T07:01:15Z

Great Job!

Works for me..... Congratulation....

nicoolaj · 2020-11-30T22:50:28Z

Works well, thanks

PraneetNeuro · 2020-12-01T02:04:46Z

Got to install Ubuntu server on a disk image but not able to boot into it. Tried passing command line arguments to set root directory, doesn't seem to work. Got any idea? stuck on initramfs.

rossbachp · 2020-12-01T04:30:15Z

I use this to install the initramfs

mkdir /mnt
mount /dev/vda /mnt
chroot /mnt

touch /etc/cloud/cloud-init.disabled

echo 'root:root' | chpasswd

echo "m1silicon" >/etc/hostname
ssh-keygen -f /etc/ssh/ssh_host_rsa_key -N '' -t rsa
ssh-keygen -f /etc/ssh/ssh_host_dsa_key -N '' -t dsa
ssh-keygen -f /etc/ssh/ssh_host_ed25519_key -N '' -t ed25519

cat <<EOF > /etc/netplan/01-dhcp.yaml 
network:
    renderer: networkd
    ethernets:
        enp0s1:
            dhcp4: true
    version: 2
EOF

exit
umount /dev/vda

CTRL-C inside the VM

Then boot with disk:

$ vftool -k vmlinux -i initrd -d ubuntu-20.04-disk.img -m 1024 -a "console=hvc0 root=/dev/vda"

I did this with qemu-img installed using brew
To increase the disk by 50Gb
qemu-img resize disk.img +50G

Then, you will need to resize the fs

PraneetNeuro · 2020-12-01T19:06:27Z

Were you able to boot into the disk? I always end up with the live version? If so, how did you manage to get it boot from the disk as the root! Any help is very much appreciated!

rossbachp · 2020-12-01T21:33:49Z

Now docker is running at the vm.
Install the docker cli (Rosetta) and use an docker ssh context.
Docker Engine is now directly available via at my Visual Studio Code.

Container Hacking is possible at the M1....

Can I help to document the setup?

rossbachp · 2020-12-01T21:37:12Z

Were you able to boot into the disk? I always end up with the live version? If so, how did you manage to get it boot from the disk as the root! Any help is very much appreciated!

It is a two phase boot process.

Frist boot with RAM disk and create the /dev/vda manually without login
Second boot with disk (add the root=/dev/vda parameter), is a normal boot with login

PraneetNeuro · 2020-12-02T04:19:04Z

Thanks a ton! But if I reboot won’t I lose the changes since we’re not writing the changes! Correct me if I’m wrong! Can you walk me through the process? That’d be of great help

mibosshard · 2020-12-03T08:58:39Z

a few days ago I created a turn-key ready bundle containing SimpleVM and Ubuntu. the image works with vftool, too:

dguerri · 2020-12-03T22:16:49Z

fwiw, it's not necessary to install qemu (and homebrew on rosetta).
Just appending data on the cloud image is enough.
I used truncate -s 20G focal-server-cloudimg-arm64.img (truncate needs to be installed, for instance via macports), but a plain >> should be enough

Then:

root@ubuntu:~# resize2fs /dev/vda
resize2fs 1.45.5 (07-Jan-2020)
Filesystem at /dev/vda is mounted on /; on-line resizing required
old_desc_blocks = 1, new_desc_blocks = 3

Any clues on what might be happening? Thanks!

@rpvilao Are you in a tmux session by chance?

rpvilao · 2020-12-10T19:16:39Z

@pgib thanks for replying. I am using a regular terminal session (zsh)

rpvilao · 2020-12-10T19:18:45Z

@pgib your question gave me an idea... I opened the terminal using rosetta (to make it work with brew), without rosetta it works thanks :)

I've enabled the "Discussions" GitHub feature which may be of use to capture some of the good info people have provided in this issue. I've noticed a bunch of Linux setup questions posed as vftool issues -- strictly we should create issues only for vftool bugs/requests (otherwise bugs are likely to get lost). I'm glad folks are helping each other out (thanks!), so the wiki/discussions should be a useful place to do this (and would make general Linux tips/info easier to find).

any hints to debugging this?

@shroomist iTerm? it uses tmux, if so ...

Does anyone feel that the IO speed in the Ubuntu OS is too slow? It shouldn't be related to the image.

yep, definitely slower than it should be...

hey @rossbachp , Ive followed your guide - all works fine.
except, as soon as I try to use apt-get install I get

[code]
Setting up flash-kernel (3.98ubuntu12) ...
flash-kernel: deferring update (trigger activated)
Processing triggers for flash-kernel (3.98ubuntu12) ...

any thoughts?

Another way to resize image(without qemu):

cp ubuntu.img ubuntu2.img 
cp ubuntu.img ubuntu3.img 

truncate -s 40G ubuntu.img
# attach ubuntu2.img as /dev/vda,  ubuntu3.img as /dev/vdb, and ubuntu.img as /dev/vdc
# /dev/vdc is the 40GB img 

vftool -k vmlinux -i initrd -d ubuntu2.img -d ubuntu3.img -d ubuntu.img -m 4096 -a "console=hvc0 root=/dev/vda init=/bin/bash"

#attach to the  tty using screen
# ...
mkfs.ext4 -L cloudimg-rootfs /dev/vdc 
mount -o ro /dev/vdb /home
mount /dev/vdc /mnt
cp -ar /home/* /mnt/
umount /mnt /home

#shutdown the VM by killing the vtftool.

rm ubuntu2.img ubuntu3.img

Then we have the ubuntu.img in 40GB size.

tommythorn · 2020-12-15T05:34:36Z

I did it way simpler using dd to append 20 GB of zeros to the img file (truncate may work just as well), booted the VM, and used resize2fs to resize the filesystem (live!).

I try the ubuntu server installer.

With screen attaching the pts, the terminal is unusable.
With arg "-t 0", if add cfmakeraw for STDIN_FILENO, the terminal works!

Following exaclty #2 (comment) on Macbook Pro 2019 (Intel) using zsh. I get the error everyone else is getting -

Any help would be super appreciated!

jasmas · 2020-12-30T21:07:18Z

I'm having the issue where the VM will not start as well.
I notice the following two sandbox errors just before vftool exits after I connect to the tty:

Sandbox: com.apple.Virtua(8285) deny(1) syscall-unix 220
Sandbox: com.apple.Virtua(8285) deny(1) syscall-unix 338

Could these be related?
This appears to be an issue with focal because I can boot bionic fine.

eugene-s · 2021-01-12T18:55:55Z

I've found the solution for the problem with:

--- VM start error: Error Domain=VZErrorDomain Code=1 "The virtual machine failed to start" UserInfo={NSDebugDescription=The virtual machine failed to start}

I was trying to update the network configuration file:

sudo nano /Library/Preferences/SystemConfiguration/com.apple.vmnet.plist

        <key>Shared_Net_Address</key>
        <string>192.168.64.1</string>
        <key>Shared_Net_Mask</key>
        <string>255.255.255.0</string>

The first vmnet had been 192.168.64.1, after running vftool the IP address was increased to 192.168.65.1 and it started failing on running. When I've changed the IP to 192.168.64.1, it started working again. Maybe you need to clean up the file /var/db/dhcpd_leases.

I suggest making backups before doing changes in those files.

jedahan · 2021-01-12T19:53:42Z

I made a small makefile that does the bare minimum in downloading, extracting, and running vftool for ubuntu images, in case that's helpful.

Just a heads up - if your vm immediately exits, make sure you have downloaded the arm64 ubuntu image, not the amd64 ubuntu image if you are on an M1 mac. Spent an embarrassingly long time with that small issue.

Is there a way to make share folders between host and guest?

adrian-azad · 2021-03-20T23:27:46Z

For the people with the VM start error: Error Domain=VZErrorDomain Code=1 "The virtual machine failed to start" UserInfo={NSDebugDescription=The virtual machine failed to start} error, It is possible that you have a problem with the files you provide, for example you forgot to gunzip vmlinuz
At least that was my problem 🤦

mungler · 2021-04-15T23:32:20Z

In case it helps anyone, as I was tearing my hair out a bit trying to get a consistent setup on Intel and ARM Macs, for our developers... it seems the intel vmlinuz file is compressed differently to the ARM one and does NOT need uncompressed before use.

If it helps anyone, here's the full steps for setting up an ubuntu 20.04 server on both intel and arm macs:
