seems unlikely since the code that is executed is actually the same, regardless if you call it manually or via the schedule. (it is possible something interferes there though)

but, from the logs:

it seems like this is a hardware/cpu error? did you maybe install a newer kernel since the last crash of the vm ?

[/código]

parece que esto es un error de hardware/cpu? ¿Quizás instaló un kernel más nuevo desde el último bloqueo de la máquina virtual?

Yes, I have kernel 5.15.12 (beta), and worked it fine before install. It is possible that the problem is kernel.

I rebooted Node and VM when was install kernel, but this happend after

I have a similar issue here: https://forum.proxmox.com/threads/b...ning-but-vm-never-starts-after-finish.104055/

when setting up scheduler to backup using snapshot mode it starts to backup freezes the VM Thaws the VM but my websites on that VM are down.. I have to manually stop and start the VM in order for it to work.

I have not tried manual backup snapshot mode, but will try it now and see if that starts the VM again without having to manually stop and start the VM.

just a note if I use scheduler with Stop mode. it works and after the backup it starts the VM itself and my sites go back online. Only the Snapshot mode in scheduler creates this issue for me.

Thanks and sorry not trying to hijack the OP's post.

Kind Regards,
Spiro
 
hey,

can you try applying the following diff to see if it fixes the issue:
Code: 
diff --git a/PVE/QemuServer.pm b/PVE/QemuServer.pm
index 0071a06..bb78fac 100644
--- a/PVE/QemuServer.pm

     my $machine_type_min = $machine_type;
     if ($add_pve_version) {

you can edit /usr/share/perl5/PVE/QemuServer.pm and then do a systemctl reload pvedaemon followed by stop/start of the affected VM.

also it would help us with identifying the issue if you could provide the following info:
* CPU model (lscpu)
* is this a nested setup? (are you running PVE on another hypervisor? if so, which?)
* which PVE kernel version is running? uname -a on the PVE host

I rented a server they installed Debian - Proxmox
i use Proxmox to make a VM
installed AlmaLinux 8.5 and cPanel copied over my websites from another server.
not sure what means nested setup ? or another hypervisor ?

Linux proxmox 5.13.19-3-pve #1 SMP PVE 5.13.19-7 (Thu, 20 Jan 2022 16:37:56 +0100) x86_64 GNU/Linux

thanks for your help

yes that's how i meant :) basically if your PVE is running on bare metal or not.

you change that single line with the - to the one below with + (so you just comment out the if part and add a semicolon before the comment, the file is located in the path i've mentioned before)

- push @$machineFlags, 'smm=off' if should_disable_smm($conf, $vga); + push @$machineFlags, 'smm=off'; #if should_disable_smm($conf, $vga);
Click to expand...
so just this line with the -
Code: 
push @$machineFlags, 'smm=off' if should_disable_smm($conf, $vga);

and replace with the + line
Code: 
push @$machineFlags, 'smm=off'; #if should_disable_smm($conf, $vga);

ok will try now and try again and report back in a few mins thanks so much

I did not even notice any stop on my websites :) it was so super fast.

froze, thawed and started backup right away



@oguz is this going to get fixed next update? or will I have to redo the fix if any updates happen?


This is great news, I am so happy. I wish anyone else finds this will help them
until you can make a change and update for everyone

Thank you Thank You so much

Kind Regards
Spiro

we'll see about a fix, this was more of a test (still need to find the root cause and do some testing for different setups, that's why i asked for CPU model and kernel version too) :)

your CPU is pretty old, so i was thinking that could be the issue here. [0]

most likely we will make an option to enable/disable smm on a VM basis, so that it can be tweaked when the hardware is too old/buggy ;)

in the meantime if there's an update on qemu-server package you'd have to reapply this fix.

Last Question please?

- How will I know if there is an update - option ? or fix for my kind of server?

because if the system updates by itself my websites will be down without my knowledge from 3am until I wake up and check them?

( or will this only update if I do apt-get update - apt-get dist-upgrade etc.

thanks again
Spiro

system shouldn't upgrade by itself in the default configuration :)

for checking what's going to be upgraded, you can see it on the GUI, or just do apt update && apt list --upgradable to get a list ;)

upgrades won't happen unless you do it.

seems like a different issue? is there any error or indication that the VM is crashing?

the fs-freeze just takes some time, and if you interrupt the backup that makes it only worse ;)
 
@oguz I stopped the backup and now it says AlmaLinux VM is Locked, all websites are down and it wont let me stop or start the VM,
it give error: VM is Locked (Backup_)
 
qm unlock VMID (change VMID to 104 for your VM)
