Thanks for this, killing traceroute worked for me. Strangely, the same traceroute command executed successfully when I switched to tty3 while the original was still stuck.

I encountered this issue for the first time installing ProxMox on a laptop with DHCP IP. However, this is also the first time I am installing ProxMox on other than server grade hardware. Didn't have this problem when the network cable was unplugged. The ethernet adapter is a very common Realtek...

Users had been complaining about laggy VM performace on our HDD-based Ceph pool. With many users VMs having many applications that are logging to disk, I see a lot of small writes with write IOPS > 5x read IOPS. Reading up here and elsewhere, it seems that Write-back may yield better...

On my ProxMox cluster, after checking with our Oracle DBA team, was to have a "storage VM" ( I believe this is what others refer to as an iSCSI portal ) that exports the drives to the two RAC nodes for use. My understanding is that Oracle ASM handles concurrent access to the data files. The...

Thanks, I have no idea why I got confused with the subscription support.

Thanks, unfortunately, I just realized there is no free version for PBS and the subscription cost is above the target budget after accounting for the remote storage costs. So I need to look at alternatives.

Just to get this clear, you have a Windows VM running in a ProxMox environment that is running in a VMWare environment running on a Windows PC?

I'm looking into implementing additional backups for a basic Proxmox host (no Ceph/SAN). Currently it's just rsync to another physical non-Proxmox machine and that machine died thus prompting a look into additional offsite backup. The initial plan was to backup to a remote storage like...

I think this is the same approach I found previously, which requires multiple QXL devices to added to the VM but ProxMox by default doesn't support this functionality. p.s. I am blind, missed the part in the doc where it teaches how to enable multiple QXL. The option is to switch the Display type

Thanks, this looks interesting but seems to be Windows only. However, this gave me a direction to look into and found some other tools that work on Linux. A few like RemotePC and Nomachine are commercial software but this free and OSS app https://remmina.org/ had been reported on reddit to work...

Has anybody tried or is it possible to run a VM that uses multiple monitors for extended desktop? i.e. able to drag an application window from one screen to another. In normal kvm/libvirt, it seems that this is possible by adding QXL devices. However, the ProxMox interface does not appear to...

I encountered this issue after my active manager crashed. The active manager apparently restarted and continued being active but I guess wasn't all good. Stopping the active manager and waiting for the standby to take over resolved this problem. After that, I started the original active manager...

Thanks for the reply, that is basically what I did after discovering that qemu64 enables the lafh-lm flag. I changed the custom CPU model from reporting as kvm64 to qemu64 and all the flags for x86-64v2 showed up correctly inside the VM.

Using qm showcmd when the CPU is set to default kvm64, I see that the lafh_lm flag is actually configured already: -cpu kvm64,enforce,+kvm_pv_eoi,+kvm_pv_unhalt,+lahf_lm,+sep \ lscpu inside VM fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht...

There is no error. The VM can be started up but when I check the output of lscpu, there lafh-lm flag is missing. The rest of the additional flags appear as expected.

As I had to get that task done quickly back then, I simply extended my script to generate the commands to create the VM and attach the disks.

Using PVE 7.2. For max live migration compatibility I had been sticking to kvm64 but some requirements now need some VMs to use x86-64v2 spec. The flags used for the cpu model inside cpu-models.conf are: flags: +cx16;+lahf-lm;+popcnt;+sse4.1;+sse4.2;+ssse3 I was able to enable all the other...

Overlooked reporting back on this issue. The root cause was actually in the message but misunderstood due to the context of me using ZFS only on that node. ProxMox complaining about unable to activate local_zfs is because the disk for ZFS was dead. Once the disk issue was fixed, the migration...

@fabian Thanks for the confirmation. I was able to move the VM back to OLD_NODE then delete the snapshots/disks. To verify that everything is now OK, I use the GUI to migrate the shutdown VM to NEW_NODE and then tried to migrate it back to OLD_NODE. Since there are no longer any snapshot or...

I shutdown the VM cleanly. Executed the command on the old node as well as on the new node. No output on the command line but from web UI, I can see the task appear in the log and fails with the same reason. Can I simply move a conf file or something from <CURRENT_NODE> to <OLD_NODE>? Tried to...
