How to launch Termina VM directly through crosvm from the host's terminal?

[Carlos Santa]

Hi:

Is it possible to launch Termina VM directly through crosvm from the host's terminal?, what would the command look like? 

This is the command I am using:

crosvm run -r /run/imageloader/termina-dlc/package/root/vm_rootfs.img -c 4 -m 1024 -s /run --cid 5 --host_ip 100.115.92.25 --netmask 255.255.255.252 --mac d2:47:f7:c5:9e:53 /run/imageloader/termina-dlc/package/root/vm_kernel

However, I am unable to get to the shell as maitred fails to notify to the system that the VM is up:

[    0.775775] maitred: Failed to notify host system that VM is ready: Socket closed

Below is the entire dmesg from the VM:

Regards,

CS

localhost ~ # crosvm run -r /run/imageloader/termina-dlc/package/root/vm_rootfs.img -c 4 -m 1024 -s /run --cid 5 --host_ip 100.115.92.25 --netmask 255.255.255.252 --mac d2:47:f7:c5:9e:53 /run/imageloader/termina-dlc/package/root/vm_kernel

Hi Carlos,

You can't (easily) start a fully-functional Termina VM with all of the guest integration from the shell by running crosvm directly.  There are several other Crostini-related daemons on the system that won't know about your manually started VM; in particular, maitred's error message is indicating that it is failing to communicate with concierge to inform it that the VM has started, since concierge didn't launch the VM in question.  There is some more Chrome OS developer-oriented information about the Crostini daemons here: https://chromium.googlesource.com/chromiumos/docs/+/HEAD/crostini_developer_guide.md

If you just want to start a basic VM without the Chrome OS integration, you can use the Termina disk image and kernel and launch a barebones shell instead of maitred, something like this:

  crosvm run -r /run/imageloader/termina-dlc/package/root/vm_rootfs.img -c 4 -m 1024 -p init=/bin/bash /run/imageloader/termina-dlc/package/root/vm_kernel

However, that will only have the read-only root filesystem and no other storage, and it won't have any of the normal Chrome OS UI integration, so it is only really appropriate for basic testing of the VM.

Could you expand on what you would like to accomplish by running the VM manually?

Hi Daniel,

<  crosvm run -r /run/imageloader/termina-dlc/package/root/vm_rootfs.img -c 4 -m 1024 -p init=/bin/bash /run/imageloader/termina-dlc/package/root/vm_kernel

Yes, thank you, that works for manually launching the VM but as you've said the shell it's pretty minimal and readonly, so unfortunately I can't do much with it, for example, none of the files under /proc are available, is this normal?

<Could you expand on what you would like to accomplish by running the VM manually?

Yes, I was forced this route because I couldn't figure out a way to get some debug or log messages out when issuing 'vmc start termina' command to start a VM with some modifications I've done to it.

For example, I'd like to add a new parameter (--vfio) that gets passed into the crosvm command, and even though I was able to patch vm_host_tools and cros deploy onto the target, the VM fails to  launch but silently fails. I need a way to see the logs as the VM is getting launched, and the only way I could think of was by manually launching the crosvm with the new parameter added, but I've discovered it's not a trivial task to launch the VM manually....

What do u suggest about getting the logs during the launching of the VM?

Here is what I'd like to accomplish:

1. Need to patch crosvm to add --vfio as an extra parameter 

2. Then pass another parameter to the kernel's boot arg : vmc start --dlc-id=termina-dlc --kernel "/mnt/stateful_partition/img_test/vm_kernel" --kernel-param "pci=lastbus=255" --no-start-lxd termina 

3. After I get the shell back, do a quick test with lspci where the new PCI dev I am trying to passthrough is listed

Thanks

Yes, this is normal; since the normal init process is not running, you would have to do any setup manually, e.g. to get a bare minimum of /proc and /sys mounted:

  mount -t proc proc /proc

  mount -t sysfs sys /sys

Logs from VM startup have been redirected to a daemon-specific log in recent Chrome OS versions; if you are already in dev mode, you should be able to access them at /home/root/<USER_HASH>/crosvm/log/dGVybWluYQ==.log (the last part is just base64("termina").

You can also see these logs in chrome://system (search for crosvm.log) even if not in dev mode.

3. After I get the shell back, do a quick test with lspci where the new PCI dev I am trying to passthrough is listed

If you are already set up to use cros deploy, the easiest method would be to modify concierge to add the new arguments to the crosvm command line and deploy vm_host_tools as described in https://chromium.googlesource.com/chromiumos/docs/+/HEAD/crostini_developer_guide.md#Host-service-changes

Then, combined with the logs mentioned above, you should be able to get the necessary information from a normal Crostini startup (such as launching Terminal) and have all of the usual tools from the container.

Unfortunately the termina rootfs image does not have lspci, so you would not be able to use it when booted manually with vm_rootfs.img unless you use a different rootfs or add another disk with extra tools.
