[Kernel-packages] [Bug 1873809] Re: Make linux-kvm bootable in LXD VMs

2020-08-25 Thread Christopher Townsend
Both the 18.04 & 16.04 Ubuntu Minimal cloud images use the kvm kernel by
default, so we need this fix applied to those kernels as well.  Are
there plans for that so that we can use those Minimal images in LXD?

Title:
  Make linux-kvm bootable in LXD VMs

Status in cloud-images:
  Invalid
Status in linux-kvm package in Ubuntu:
  Fix Released
Status in linux-kvm source package in Focal:
  Fix Released

Bug description:
  The `disk-kvm.img` images which are to be preferred when run under
  virtualization, currently completely fail to boot under UEFI.

  A workaround was put in place such that LXD instead will pull generic-
  based images until this is resolved, this however does come with a
  much longer boot time (as the kernel panics, reboots and then boots)
  and also reduced functionality from cloud-init, so we'd still like
  this fixed in the near future.

  To get things behaving, it looks like we need the following config
  options to be enable in linux-kvm:

   - CONFIG_EFI_STUB
   - CONFIG_VSOCKETS
   - CONFIG_VIRTIO_VSOCKETS
   - CONFIG_VIRTIO_VSOCKETS_COMMON

  == Rationale ==
  We'd like to be able to use the linux-kvm based images for LXD, those will 
directly boot without needing the panic+reboot behavior of generic images and 
will be much lighter in general.

  We also need the LXD agent to work, which requires functional virtio
  vsock.

  == Test case ==
   - wget 
http://cloud-images.ubuntu.com/focal/current/focal-server-cloudimg-amd64-lxd.tar.xz
   - wget 
http://cloud-images.ubuntu.com/focal/current/focal-server-cloudimg-amd64-disk-kvm.img
   - lxc image import focal-server-cloudimg-amd64-lxd.tar.xz 
focal-server-cloudimg-amd64-disk-kvm.img --alias bug1873809
   - lxc launch bug1873809 v1
   - lxc console v1
   - 
   - 
   - lxc exec v1 bash

  To validate a new kernel, you'll need to manually repack the .img file
  and install the new kernel in there.

  == Regression potential ==
  I don't know who else is using those kvm images right now, but those changes 
will cause a change to the kernel binary such that it contains the EFI stub 
bits + a signature. This could cause some (horribly broken) systems to no 
longer be able to boot that kernel. Though considering that such a setup is 
common to our other kernels, this seems unlikely.

  Also, this will be introducing virtio vsock support which again, could
  maybe confused some horribly broken systems?

  
  In either case, the kernel conveniently is the only package which ships 
multiple versions concurently, so rebooting on the previous kernel is always an 
option, mitigating some of the risks.

  
  -- Details from original report --
  User report on the LXD side: https://github.com/lxc/lxd/issues/7224

  I've reproduced this issue with:
   - wget 
http://cloud-images.ubuntu.com/focal/current/focal-server-cloudimg-amd64-disk-kvm.img
   - qemu-system-x86_64 -bios /usr/share/ovmf/OVMF.fd -hda 
focal-server-cloudimg-amd64-disk-kvm.img -m 1G

  On the graphical console, you'll see EDK2 load (TianoCore) followed by basic 
boot messages and then a message from grub (error: can't find command 
`hwmatch`).
  Those also appear on successful boots of other images so I don't think 
there's anything concerning that. However it'll hang indefinitely and eat up 
all your CPU.

  Switching to the text console view (serial0), you'll see the same
  issue as that LXD report:

[Kernel-packages] [Bug 1873809] Re: Make linux-kvm bootable in LXD VMs

2020-08-24 Thread Stéphane Graber
We weren't planning to as the previous releases (xenial and bionic) did
not have "-kvm" image and their default image includes an initrd making
them boot just fine under LXD.

So it's really just groovy+focal that we need before we can start using those 
images.
focal has been taken care of so we're just waiting for linux-kvm to hit the 
release pocket on groovy before we can switch over to those.

[Kernel-packages] [Bug 1873809] Re: Make linux-kvm bootable in LXD VMs

2020-06-29 Thread Stefan Bader
@Stéphane, right now (and that might be for a while still) the linux-kvm
kernel in Groovy is a copy-forward from Focal. So once this releases,
you should be able to use it there as well. I started to have annotated
config enforcement for the adjusted config which hopefully will survive
when the specific kvm kernel for Groovy gets started.

  Make linux-kvm bootable in LXD VMs

Status in cloud-images:
  Invalid
Status in linux-kvm package in Ubuntu:
  Triaged
Status in linux-kvm source package in Focal:
  Fix Committed

Bug description:
  The `disk-kvm.img` images which are to be preferred when run under
  virtualization, currently completely fail to boot under UEFI.

  A workaround was put in place such that LXD instead will pull generic-
  based images until this is resolved, this however does come with a
  much longer boot time (as the kernel panics, reboots and then boots)
  and also reduced functionality from cloud-init, so we'd still like
  this fixed in the near future.

  To get things behaving, it looks like we need the following config
  options to be enable in linux-kvm:

   - CONFIG_EFI_STUB
   - CONFIG_VSOCKETS
   - CONFIG_VIRTIO_VSOCKETS
   - CONFIG_VIRTIO_VSOCKETS_COMMON

  == Rationale ==
  We'd like to be able to use the linux-kvm based images for LXD, those will 
directly boot without needing the panic+reboot behavior of generic images and 
will be much lighter in general.

  We also need the LXD agent to work, which requires functional virtio
  vsock.

  == Test case ==
   - wget 
http://cloud-images.ubuntu.com/focal/current/focal-server-cloudimg-amd64-lxd.tar.xz
   - wget 
http://cloud-images.ubuntu.com/focal/current/focal-server-cloudimg-amd64-disk-kvm.img
   - lxc image import focal-server-cloudimg-amd64-lxd.tar.xz 
focal-server-cloudimg-amd64-disk-kvm.img --alias bug1873809
   - lxc launch bug1873809 v1
   - lxc console v1
   - 
   - 
   - lxc exec v1 bash

  To validate a new kernel, you'll need to manually repack the .img file
  and install the new kernel in there.

  == Regression potential ==
  I don't know who else is using those kvm images right now, but those changes 
will cause a change to the kernel binary such that it contains the EFI stub 
bits + a signature. This could cause some (horribly broken) systems to no 
longer be able to boot that kernel. Though considering that such a setup is 
common to our other kernels, this seems unlikely.

  Also, this will be introducing virtio vsock support which again, could
  maybe confused some horribly broken systems?

  
  In either case, the kernel conveniently is the only package which ships 
multiple versions concurently, so rebooting on the previous kernel is always an 
option, mitigating some of the risks.

  
  -- Details from original report --
  User report on the LXD side: https://github.com/lxc/lxd/issues/7224

  I've reproduced this issue with:
   - wget 
http://cloud-images.ubuntu.com/focal/current/focal-server-cloudimg-amd64-disk-kvm.img
   - qemu-system-x86_64 -bios /usr/share/ovmf/OVMF.fd -hda 
focal-server-cloudimg-amd64-disk-kvm.img -m 1G

  On the graphical console, you'll see EDK2 load (TianoCore) followed by basic 
boot messages and then a message from grub (error: can't find command 
`hwmatch`).
  Those also appear on successful boots of other images so I don't think 
there's anything concerning that. However it'll hang indefinitely and eat up 
all your CPU.

  Switching to the text console view (serial0), you'll see the same
  issue as that LXD report:

@smb what's the state of groovy, did you push the config update there
too?

For the cloud images, we'll want to switch over to those using linux-kvm
in groovy first, then focal, so just want to make sure we'll get a
working kernel on there too!

Latest version: 5.4.0-1018-kvm

This bug is awaiting verification that the kernel in -proposed solves
the problem. Please test the kernel and update this bug with the
results. If the problem is solved, change the tag 'verification-needed-
focal' to 'verification-done-focal'. If the problem still exists, change
the tag 'verification-needed-focal' to 'verification-failed-focal'.

If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

Title:
  Make linux-kvm bootable in LXD VMs

Status in cloud-images:
  Invalid
Status in linux-kvm package in Ubuntu:
  Triaged
Status in linux-kvm source package in Focal:
  Fix Committed

Bug description:
  The `disk-kvm.img` images which are to be preferred when run under
  virtualization, currently completely fail to boot under UEFI.

  A workaround was put in place such that LXD instead will pull generic-
  based images until this is resolved, this however does come with a
  much longer boot time (as the kernel panics, reboots and then boots)
  and also reduced functionality from cloud-init, so we'd still like
  this fixed in the near future.

  To get things behaving, it looks like we need the following config
  options to be enable in linux-kvm:

   - CONFIG_EFI_STUB
   - CONFIG_VSOCKETS
   - CONFIG_VIRTIO_VSOCKETS
   - CONFIG_VIRTIO_VSOCKETS_COMMON

  == Rationale ==
  We'd like to be able to use the linux-kvm based images for LXD, those will 
directly boot without needing the panic+reboot behavior of generic images and 
will be much lighter in general.

  We also need the LXD agent to work, which requires functional virtio
  vsock.

  == Test case ==
   - wget 
http://cloud-images.ubuntu.com/focal/current/focal-server-cloudimg-amd64-lxd.tar.xz
   - wget 
http://cloud-images.ubuntu.com/focal/current/focal-server-cloudimg-amd64-disk-kvm.img
   - lxc image import focal-server-cloudimg-amd64-lxd.tar.xz 
focal-server-cloudimg-amd64-disk-kvm.img --alias bug1873809
   - lxc launch bug1873809 v1
   - lxc console v1
   - 
   - 
   - lxc exec v1 bash

  To validate a new kernel, you'll need to manually repack the .img file
  and install the new kernel in there.

  == Regression potential ==
  I don't know who else is using those kvm images right now, but those changes 
will cause a change to the kernel binary such that it contains the EFI stub 
bits + a signature. This could cause some (horribly broken) systems to no 
longer be able to boot that kernel. Though considering that such a setup is 
common to our other kernels, this seems unlikely.

  Also, this will be introducing virtio vsock support which again, could
  maybe confused some horribly broken systems?

  
  In either case, the kernel conveniently is the only package which ships 
multiple versions concurently, so rebooting on the previous kernel is always an 
option, mitigating some of the risks.

  User report on the LXD side: https://github.com/lxc/lxd/issues/7224

  I've reproduced this issue with:
   - wget 
http://cloud-images.ubuntu.com/focal/current/focal-server-cloudimg-amd64-disk-kvm.img
   - qemu-system-x86_64 -bios /usr/share/ovmf/OVMF.fd -hda 
focal-server-cloudimg-amd64-disk-kvm.img -m 1G

  On the graphical console, you'll see EDK2 load (TianoCore) followed by basic 
boot messages and then a message from grub (error: can't find command 
`hwmatch`).
  Those also appear on successful boots of other images so I don't think 
there's anything concerning that. However it'll hang indefinitely and eat up 
all your CPU.

  Switching to the text console view (serial0), you'll see the same

2020-06-24 Thread Stefan Bader
Alright, at least partially understanding things now. So it looks like
"Decoding failed" happens generally on some platforms (and I do not
understand still why this is). The difference between the generic kernel
and the kvm kernel is that the kvm kernel has a built-in BLK_DEV_RAM of
size (4096) whereas the generic kernel uses a module for that.

It looks like only if BLK_DEV_RAM=y is set, the code which populates the
initial rootfs does try to flush and refill the ramdisk device.
Otherwise the partially expanded rootfs is retained. And I guess the
ramdisk size is set to small so we get the incomplete write there.

I guess the solution (which does not solve the decode failure) is to
change the kvm kernel config to

BLK_DEV_RAM=m
CONFIG_BLK_DEV_RAM_SIZE=65536

2020-06-24 Thread Stefan Bader
Ok, so with the same software versions installed but on a different hw
platform, I did at least once get this incomplete write error. The
working box is an AMD/BIOS one and the non-working an Intel/EFI. Not
sure why that has any impact.

Hm, and maybe also relevant: what kind of pool is used? My setup was
"lxd init --auto" which is a file based image backend.

2020-06-24 Thread Stefan Bader
@Stéphane, I have now followed your steps from commant #38 (was using the 
official ubuntu image before with cloud-init and that does a initrd-less boot 
first which is successful for me) but this does not show me the error you see 
either. And a break=top does work (with some complaints about tty1 which is 
expected due to the missing efi-fb).
I double-checked the initramfs compression setting and that is lz4.

This is rather weird. I will try on a different hw but that really
should not be relevant. For double checking: which LXD version are you
using? I am on the focal/stable/4.0 stream:

lxd4.0.115682  4.0/stable/… canonical✓

It's not the log above clearly shows the kernel loading an initrd.

[Kernel-packages] [Bug 1873809] Re: Make linux-kvm bootable in LXD VMs

2020-06-23 Thread Guilherme G. Piccoli
I'm not sure if it's related, but maybe worth the mention: could this be
due to the initrd-less boot? I've noticed that in some VMs, it first
fails to boot (it tries an initrd-less boot), reboots and then loads the
initrd. This is an Ubuntu grub-thing, and you can prevent that by
deleting a file *40*partuuid* form /etc/default/grub.d/ (need to
recreate grub config file after that).

Cheers,


Guilherme

  I've reproduced this issue with:
   - wget 
http://cloud-images.ubuntu.com/focal/current/focal-server-cloudimg-amd64-disk-kvm.img
   - qemu-system-x86_64 -bios /usr/share/ovmf/OVMF.fd -hda

  On the graphical console, you'll see EDK2 load (TianoCore) followed by basic 
boot messages and then a message from grub (error: can't find command 
`hwmatch`).
  Those also appear on successful boots of other images so I don't think 
there's anything concerning that. However it'll hang indefinitely and eat up 
all your CPU.

  Switching to the text console view (serial0), you'll see the same
  issue as that LXD report:

[Kernel-packages] [Bug 1873809] Re: Make linux-kvm bootable in LXD VMs

2020-06-23 Thread Stéphane Graber
@smb Can you confirm that your system indeed goes through the initrd and
isn't just silently falling back to directly mounting and booting /?

Booting with break=mount would likely be a valid way to test this
(should drop you in a shell).

  The `disk-kvm.img` images which are to be preferred when run under

  We'd like to be able to use the linux-kvm based images for LXD, those will

  I don't know who else is using those kvm images right now, but those changes 
will cause a change to the kernel binary such that it contains the EFI stub

Hmm, actually no luck at booting either 1015 or 1017 on
security.secureboot=false here, poked at grub and it does load both
kernel and initrd...

2020-06-23 Thread Stéphane Graber
Yeah, I think you're right, I also had the exact same panic happen now
on 1015, so it's likely some grub weirdness rather than kernel
regression.

It just so happened that in my last test I managed to get a working grub
config after moving to 1015 and not with 1017. Looks like we'll need to
poke at grub...

[Kernel-packages] [Bug 1873809] Re: Make linux-kvm bootable in LXD VMs

2020-06-23 Thread Stefan Bader
@Stéphane, the uncompress message appears to be something that may
happen if blocks are not aligned but not harming anything. By now I have
played around with both a self created secureboot VM on bionic and also
(following your turorial) a LXD 4.0 vM. And for both I could not repeat
what you saw. Both booted. There is a minor issue for people creating
their own VMs and using a graphical interface (like virt-manager). The
kvm kernel has no framebuffer devices enabled so one does not see
anything if one does not enable a serial console.


For LXD, when I repeated the steps from 
https://discuss.linuxcontainers.org/t/running-virtual-machines-with-lxd-4-0/7519
 I saw one crash not finding the root disk after the initial lxc start  when I 
ran lxc console. But that was with the generic kernel and that seems to be 
handled by the panic handler. Attaching to he console a second time I saw 
cloud-init finishing and then I installed the proposed kvm kernel in that 
running vm and rebooted. And this gave me a working boot:

  Make linux-kvm bootable in LXD VMs

Status in linux-kvm source package in Focal:
  Fix Committed

Bug description:
  The `disk-kvm.img` images which are to be preferred when run under
  virtualization, currently completely fail to boot under UEFI.

  A workaround was put in place such that LXD instead will pull generic-
  based images until this is resolved, this however does come with a
  much longer boot time (as the kernel panics, reboots and then boots)
  and also reduced functionality from cloud-init, so we'd still like
  this fixed in the near future.

  To get things behaving, it looks like we need the following config
  options to be enable in linux-kvm:

   - CONFIG_EFI_STUB
   - CONFIG_VSOCKETS
   - CONFIG_VIRTIO_VSOCKETS
   - CONFIG_VIRTIO_VSOCKETS_COMMON

  == Rationale ==
  We'd like to be able to use the linux-kvm based images for LXD, those will 
directly boot without needing the panic+reboot behavior of generic images and 
will be much lighter in general.

  We also need the LXD agent to work, which requires functional virtio
  vsock.

  == Test case ==
   - wget 
http://cloud-images.ubuntu.com/focal/current/focal-server-cloudimg-amd64-lxd.tar.xz
   - wget 
http://cloud-images.ubuntu.com/focal/current/focal-server-cloudimg-amd64-disk-kvm.img
   - lxc image import focal-server-cloudimg-amd64-lxd.tar.xz 
focal-server-cloudimg-amd64-disk-kvm.img --alias bug1873809
   - lxc launch bug1873809 v1
   - lxc console v1
   - 
   - 
   - lxc exec v1 bash

  To validate a new kernel, you'll need to manually repack the .img file
  and install the new kernel in there.

  == Regression potential ==
  I don't know who else is using those kvm images right now, but those changes 
will cause a change to the kernel binary such that it contains the EFI stub 
bits + a signature. This could cause some (horribly broken) systems to no 
longer be able to boot that kernel. Though considering that such a setup is 
common to our other kernels, this seems unlikely.

  Also, this will be introducing virtio vsock support which again, could
  maybe confused some horribly broken systems?

  
  In either case, the kernel conveniently is the only package which ships 
multiple versions concurently, so rebooting on the previous kernel is always an 
option, mitigating some of the risks.

  User report on the LXD side: https://github.com/lxc/lxd/issues/7224

  I've reproduced this issue with:
   - wget 
http://cloud-images.ubuntu.com/focal/current/focal-server-cloudimg-amd64-disk-kvm.img
   - qemu-system-x86_64 -bios /usr/share/ovmf/OVMF.fd -hda

  On the graphical console, you'll see EDK2 load (TianoCore) followed by basic 
boot messages and then a message from grub (error: can't find command 
`hwmatch`).
  Those also appear on successful boots of other images so I don't think 
there's anything concerning that. However it'll hang indefinitely and eat up 
all your CPU.

  Switching to the text console view (serial0), you'll see the same

2020-06-18 Thread Stéphane Graber
@Stefan, so actually this is an actual regression.

1015 will boot just fine in LXD with secureboot disabled.
1017 will not boot at all in LXD with or without secureboot disabled.

I don't know if it's switching to a signed kernel which causes the lz4
issue but the result is a clear regression so I would not consider this
kernel suitable for release to anyone.

2020-06-18 Thread Stefan Bader
@Stephane, if this bug was not phrased that generically I would feel
inclined to say it verified ok if the kernel image can be booted in
secureboot mode and has the requested config options set. And treat the
initrd issue as a separate one on the path to completion.

For us, I would propose to count this feedback as success (and still
release the kernel that way if there is no other problems).

Is what we're getting on current generic kernel, though boot continues after 
that.
I don't know if when that happens we're actually skipping the initrd entirely 
and just get lucky that the generic kernel has everything we need builtin so it 
boots or if the error in that case is just wrong and the initrd is still 
properly unpacked and run.

Either way, this needs sorting, looking at the other bug report, there's
been something wrong with our kernel and lz4 initrd for a long time and
it's apparently biting us a lot more now.

This appears to be lz4 related. Changing the initramfs to gzip makes the VM 
boot just fine.
It's worth noting that when booting the generic kernel, we get the unpack error 
showed in https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1835660 but 
things still boot fine.

Marking verification as failed based on this. We need images to work
properly with a standard Ubuntu config so need lz4 fixed.

  Those also appear on successful boots of other images so I don't think 
there's anything concerning that. However it'll hang indefinitely and eat up

[Kernel-packages] [Bug 1873809] Re: Make linux-kvm bootable in LXD VMs

2020-06-18 Thread Stefan Bader
This bug is awaiting verification that the kernel in -proposed solves
the problem. Please test the kernel and update this bug with the
results. If the problem is solved, change the tag 'verification-needed-
focal' to 'verification-done-focal'. If the problem still exists, change
the tag 'verification-needed-focal' to 'verification-failed-focal'.

If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

Title:
  Make linux-kvm bootable in LXD VMs

Status in cloud-images:
  Invalid
Status in linux-kvm package in Ubuntu:
  Triaged
Status in linux-kvm source package in Focal:
  Fix Committed

Bug description:
  The `disk-kvm.img` images which are to be preferred when run under
  virtualization, currently completely fail to boot under UEFI.

  A workaround was put in place such that LXD instead will pull generic-
  based images until this is resolved, this however does come with a
  much longer boot time (as the kernel panics, reboots and then boots)
  and also reduced functionality from cloud-init, so we'd still like
  this fixed in the near future.

  To get things behaving, it looks like we need the following config
  options to be enable in linux-kvm:

   - CONFIG_EFI_STUB
   - CONFIG_VSOCKETS
   - CONFIG_VIRTIO_VSOCKETS
   - CONFIG_VIRTIO_VSOCKETS_COMMON

  == Rationale ==
  We'd like to be able to use the linux-kvm based images for LXD, those will 
directly boot without needing the panic+reboot behavior of generic images and 
will be much lighter in general.

  We also need the LXD agent to work, which requires functional virtio
  vsock.

  == Test case ==
   - wget 
http://cloud-images.ubuntu.com/focal/current/focal-server-cloudimg-amd64-lxd.tar.xz
   - wget 
http://cloud-images.ubuntu.com/focal/current/focal-server-cloudimg-amd64-disk-kvm.img
   - lxc image import focal-server-cloudimg-amd64-lxd.tar.xz 
focal-server-cloudimg-amd64-disk-kvm.img --alias bug1873809
   - lxc launch bug1873809 v1
   - lxc console v1
   - 
   - 
   - lxc exec v1 bash

  To validate a new kernel, you'll need to manually repack the .img file
  and install the new kernel in there.

  == Regression potential ==
  I don't know who else is using those kvm images right now, but those changes 
will cause a change to the kernel binary such that it contains the EFI stub 
bits + a signature. This could cause some (horribly broken) systems to no 
longer be able to boot that kernel. Though considering that such a setup is 
common to our other kernels, this seems unlikely.

  Also, this will be introducing virtio vsock support which again, could
  maybe confused some horribly broken systems?

  
  In either case, the kernel conveniently is the only package which ships 
multiple versions concurently, so rebooting on the previous kernel is always an 
option, mitigating some of the risks.

  and install the new kernel in there.

  I don't know who else is using those kvm images right now, but those changes 
will cause a change to the kernel binary such that it contains the EFI stub 
bits + a signature. This could cause some (horribly broken) systems to no 
longer be able to boot that kernel. Though considering that such a setup is 
common to our other kernels, this seems unlikely.

  Also, this will be introducing virtio vsock support which again, could
  maybe confused some horribly broken systems?

multiple versions concurently, so rebooting on the previous kernel is always an 
option, mitigating some of the risks.

  User report on the LXD side: https://github.com/lxc/lxd/issues/7224

  I've reproduced this issue with:
   - wget 
http://cloud-images.ubuntu.com/focal/current/focal-server-cloudimg-amd64-disk-kvm.img
   - qemu-system-x86_64 -bios /usr/share/ovmf/OVMF.fd -hda 
focal-server-cloudimg-amd64-disk-kvm.img -m 1G

  On the graphical console, you'll see EDK2 load (TianoCore) followed by basic 
boot messages and then a message from grub (error: can't find command 
`hwmatch`).
  Those also appear on successful boots of other images so I don't think 
there's anything concerning that. However it'll hang indefinitely and eat up 
all your CPU.

  Switching to the text console view (serial0), you'll see the same
  issue as that LXD report:

@stgraber sorry I should have clarified that I'm referring to Eoan specifically.
In Eoan, EFI_STUB is still not enabled. Is it needed there?

Bug description:
  The `disk-kvm.img` images which are to be preferred when run under
  virtualization, currently completely fail to boot under UEFI.

  A workaround was put in place such that LXD instead will pull generic-
  based images until this is resolved, this however does come with a
  much longer boot time (as the kernel panics, reboots and then boots)
  and also reduced functionality from cloud-init, so we'd still like
  this fixed in the near future.

  To get things behaving, it looks like we need the following config

   - CONFIG_VSOCKETS
   - CONFIG_VIRTIO_VSOCKETS
   - CONFIG_VIRTIO_VSOCKETS_COMMON

  == Rationale ==
  We'd like to be able to use the linux-kvm based images for LXD, those will 
directly boot without needing the panic+reboot behavior of generic images and 
will be much lighter in general.

  We also need the LXD agent to work, which requires functional virtio
  vsock.

@Khaled yes, it is and we have it now. What's still needed is for the
kernel to be signed so it can be used under secureboot.

Hello,

Just tested the latest image in ./current and it boots fine :

Title:
  Make linux-kvm bootable in LXD VMs

Status in cloud-images:
  Invalid
Status in linux-kvm package in Ubuntu:
  Triaged

Bug description:
  The `disk-kvm.img` images which are to be preferred when run under
  virtualization, currently completely fail to boot under UEFI.

  A workaround was put in place such that LXD instead will pull generic-
  based images until this is resolved, this however does come with a
  much longer boot time (as the kernel panics, reboots and then boots)
  and also reduced functionality from cloud-init, so we'd still like
  this fixed in the near future.

  To get things behaving, it looks like we need the following config
  options to be enable in linux-kvm:

   - CONFIG_EFI_STUB
   - CONFIG_VSOCKETS
   - CONFIG_VIRTIO_VSOCKETS
   - CONFIG_VIRTIO_VSOCKETS_COMMON

  == Rationale ==
  We'd like to be able to use the linux-kvm based images for LXD, those will 
directly boot without needing the panic+reboot behavior of generic images and 
will be much lighter in general.

  We also need the LXD agent to work, which requires functional virtio
  vsock.

  == Test case ==
   - wget 
http://cloud-images.ubuntu.com/focal/current/focal-server-cloudimg-amd64-lxd.tar.xz
   - wget 
http://cloud-images.ubuntu.com/focal/current/focal-server-cloudimg-amd64-disk-kvm.img
   - lxc image import focal-server-cloudimg-amd64-lxd.tar.xz 
focal-server-cloudimg-amd64-disk-kvm.img --alias bug1873809
   - lxc launch bug1873809 v1
   - lxc console v1
   - 
   - 
   - lxc exec v1 bash

  To validate a new kernel, you'll need to manually repack the .img file
  and install the new kernel in there.

  == Regression potential ==
  I don't know who else is using those kvm images right now, but those changes 
will cause a change to the kernel binary such that it contains the EFI stub 
bits + a signature. This could cause some (horribly broken) systems to no 
longer be able to boot that kernel. Though considering that such a setup is 
common to our other kernels, this seems unlikely.

  Also, this will be introducing virtio vsock support which again, could
  maybe confused some horribly broken systems?

  
  In either case, the kernel conveniently is the only package which ships 
multiple versions concurently, so rebooting on the previous kernel is always an 
option, mitigating some of the risks.

  
  -- Details from original report --
  User report on the LXD side: https://github.com/lxc/lxd/issues/7224

  I've reproduced this issue with:
   - wget 
http://cloud-images.ubuntu.com/focal/current/focal-server-cloudimg-amd64-disk-kvm.img
   - qemu-system-x86_64 -bios /usr/share/ovmf/OVMF.fd -hda 
focal-server-cloudimg-amd64-disk-kvm.img -m 1G

  On the graphical console, you'll see EDK2 load (TianoCore) followed by basic 
boot messages and then a message from grub (error: can't find command 
`hwmatch`).
  Those also appear on successful boots of other images so I don't think 
there's anything concerning that. However it'll hang indefinitely and eat up 
all your CPU.

  Switching to the text console view (serial0), you'll see the same
  issue as that LXD report:

Hmm, actually, CONFIG_EFI_STUB is the one we were missing and I'm not
seeing that in your VM either, which makes me wonder how it was booted
in the first place :)

[Kernel-packages] [Bug 1873809] Re: Make linux-kvm bootable in LXD VMs

2020-04-21 Thread Louis Bouchard
Hello,
thanks for the quick turnaround.

For the record, some EFI configs did exist in prior 5.3 images :

root@focal:/boot# cat /etc/cloud/build.info
build_name: server
serial: 20200223
root@focal:/boot# uname -r
5.3.0-1009-kvm
root@focal:/boot# grep -i ^CONFIG_EFI config-5.3.0-1009-kvm 
CONFIG_EFI=y
CONFIG_EFI_VARS=y
CONFIG_EFI_ESRT=y
CONFIG_EFI_RUNTIME_WRAPPERS=y
CONFIG_EFI_EARLYCON=y
CONFIG_EFI_PARTITION=y
CONFIG_EFIVAR_FS=m

I'll be using the other image for testing in the meantime
...Louis

  Make linux-kvm bootable in LXD VMs

Status in Cloud-Bio-Linux Tutorials:
  Confirmed
Status in cloud-images:
  Confirmed
Status in linux-kvm package in Ubuntu:
  Confirmed

Bug description:
  The `disk-kvm.img` images which are to be preferred when run under
  virtualization, currently completely fail to boot under UEFI.

  A workaround was put in place such that LXD instead will pull generic-
  based images until this is resolved, this however does come with a
  much longer boot time (as the kernel panics, reboots and then boots)
  and also reduced functionality from cloud-init, so we'd still like
  this fixed in the near future.

  To get things behaving, it looks like we need the following config
  options to be enable in linux-kvm:

   - CONFIG_EFI_STUB
   - CONFIG_VSOCKETS
   - CONFIG_VIRTIO_VSOCKETS
   - CONFIG_VIRTIO_VSOCKETS_COMMON

  == Rationale ==
  We'd like to be able to use the linux-kvm based images for LXD, those will 
directly boot without needing the panic+reboot behavior of generic images and 
will be much lighter in general.

  We also need the LXD agent to work, which requires functional virtio
  vsock.

2020-04-20 Thread Stéphane Graber
Just tested it now, confirmed that this still boots fine and that this
time the LXD agent successfully starts too.

So this config seems suitable for us. That + enabling kernel signing
will get us working images.

Thanks!

[Kernel-packages] [Bug 1873809] Re: Make linux-kvm bootable in LXD VMs

2020-04-20 Thread Stéphane Graber
** Description changed:

  The `disk-kvm.img` images which are to be preferred when run under
- virtualization, completely fail to boot under UEFI.
+ virtualization, currently completely fail to boot under UEFI.
  
- This is a critical issue as those are the images that LXD is now pulling
- by default.
+ A workaround was put in place such that LXD instead will pull generic-
+ based images until this is resolved, this however does come with a much
+ longer boot time (as the kernel panics, reboots and then boots) and also
+ reduced functionality from cloud-init, so we'd still like this fixed in
+ the near future.
  
+ To get things behaving, it looks like we need the following config

+  - CONFIG_EFI_STUB
+  - CONFIG_VSOCKETS
+  - CONFIG_VIRTIO_VSOCKETS
+  - CONFIG_VIRTIO_VSOCKETS_COMMON
+ 
+ == Rationale ==
+ We'd like to be able to use the linux-kvm based images for LXD, those will 
directly boot without needing the panic+reboot behavior of generic images and 
will be much lighter in general.
+ 
+ We also need the LXD agent to work, which requires functional virtio

will cause a change to the kernel binary such that it contains the EFI stub

- Note that the non optimized images boot just fine (disk1.img).

  I've reproduced this issue with:
-  - wget 
http://cloud-images.ubuntu.com/focal/current/focal-server-cloudimg-amd64-disk-kvm.img
-  - qemu-system-x86_64 -bios /usr/share/ovmf/OVMF.fd -hda 
focal-server-cloudimg-amd64-disk-kvm.img -m 1G
- 
+  - wget

+  - qemu-system-x86_64 -bios /usr/share/ovmf/OVMF.fd -hda 
focal-server-cloudimg-amd64-disk-kvm.img -m 1G
  
  On the graphical console, you'll see EDK2 load (TianoCore) followed by basic 
boot messages and then a message from grub (error: can't find command 
`hwmatch`).
  Those also appear on successful boots of other images so I don't think 
there's anything concerning that. However it'll hang indefinitely and eat up 
all your CPU.
  
  Switching to the text console view (serial0), you'll see the same issue
  as that LXD report:
