Hi all,
I upgrade to pve-kernel-5.0.21-4-pve kernel today, now none of my linux hosts will boot.
The guests load grub, then immediately reboot after the grub timeout.

I reboot the host into pve-kernel-5.0.21-3-pve and everything works well.

I can't seem to uninstall this kernel either (I thought maybe I would just hold on pve-kernel-5.0.21-3-pve kernel):

aptitude -s purge pve-kernel-5.0.21-4-pve
The following packages will be REMOVED:
pve-kernel-5.0.21-4-pve{p}
0 packages upgraded, 0 newly installed, 1 to remove and 0 not upgraded.
Need to get 0 B of archives. After unpacking 269 MB will be freed.
The following packages have unmet dependencies:
pve-kernel-5.0 : Depends: pve-kernel-5.0.21-4-pve but it is not going to be installed
The following actions will resolve these dependencies:

Remove the following packages:
1) proxmox-ve [6.0-2 (now, stable)]
2) pve-kernel-5.0 [6.0-10 (now, stable)]

Seems like maybe the kernel wasn't correctly installed, I'd guess.

Can you do:
Code: 
apt install --reinstall pve-kernel-5.0.21-4-pve

and post the output? Maybe your /boot is to full to be able to store new kernel images? Albeit then the grub entry shouldn't be created..
 
Plenty of disk space on the host:
Code: 
df -h

Hi,

Same problem here since the kernel update : pve-kernel-5.0.21-4-pve

The reinstall doesn't do anything better.

More specific information about host HW and storage setup + guest config and OS would be really appreciated..

Just for information, before this morning and the update, the VMs were working well.

Thanks
 
Getting the same issue here but only on my Intel host (Q6600). My AMD host (Phenom II X4 955) does not have the problem.

Both are running Debian Buster with Proxmox 6 using ZFS storage for the VMs.
 
Nothing..

After a cleaning of dsmeg, just this during the startup and reboot of the VM :

Thanks
 
On the VM, the last message I managed to capture at the boot before the reboot:
Code: 
Probing EDD /edd=off to disable)... ok

that's a red herring, shouldn't be problematic.

Ah great, so my ubuntu Linux VM test are not much of use for this ...

Sorry if I just oversaw it, what Distro+version is a problematic one for you?
(I only saw gparted mounted in the first config, and that probably isn't the one installed there :) )
 
Thank you very much for your support

The problem is on Debian 9 Stretch
 
I was also using a Debian 9 guest. amd64 specifically. I've not tested with Debian 10 guests yet, but I can try tonight.
