Coming back from vacation, I indeed found a stuck Win10 VM. Unfortunately I only noticed it now and I also cannot say how long it has been stuck, because this is an unmonitored VM. The VM doesn't have the proposed mitigations=off configured, because this has come up only during my vacation...

ok, then I will open an support ticket the next time one of our VMs freezes. Not sure how fast it happens, but it will, sooner or later ... I'll keep you posted.

Would it help if you got access to one of the nodes when the freeze occurs? If so, I'd be happy to upgrade that node to Basic support and open an official support request. I guess others would be happy to do the same, because this is really growing into a showstopper.

that's exactly what we're seeing as well. The freezing guests can be tight on memory and we have tried with and without memory ballooning, all to no avail.

At least for us, changing it from "VirtIO SCSI" to "VirtIO SCSI single" has made the biggest difference. We've been seeing far less freezes than before ... but as we all know, only time will tell if this really improves things ... And "VirtIO SCSI single" is actually also the default now.

while we have been "lucky" during the last days, not seeing any recent freezes, what puzzles me is that even a watchdog is not able to interact with such a frozen VM. That is, no matter what has been configured (eg. reboot), the VM is and remains frozen. As far as I understand how the kernel...

We're probably in the same boat as well, we're seing some very high load Debian 11 VMs (high load on CPU, RAM and I/O) freezing randomly. Sometimes they run without issues for weeks and sometimes they crash after days following a reboot. In our case, the common determinator is that they run on...

well, I dug a bit deeper as well and it looks like as if the version of the ureq HTTPS client used (as indicated in the exception /usr/share/cargo/registry/ureq-2.4.0/) is outdated. There is a fix for dealing with those "UnsupportedCriticalExtension" since ureq 2.6.0...

Allright, after temporarily removing the local CA certificates from /usr/local/share/ca-certificates and running "update-ca-certificates --fresh" again, pvesubscription update successfully completes. So the issue must have something to do with those custom CA certificates, but as they have been...

yes, there are some local CA certificates in that directory. They have been put there in Nov 2019, so that's quite a while :) I however noticed that one of the certificates didn't have .crt but .pem as a filename extension. After listing all known certificates from...

thanks. I can ping & connect to shop.proxmox.com on the node's commandline, but "pvesubscription update" throws an ugly exception: root@sisyphos:~# RUST_BACKTRACE=full pvesubscription update thread '<unnamed>' panicked at 'Failed to add native certificate too root store...

Hi, one of our nodes feels unhappy about its subscription state and displays "invalid: subscription information too old" in the node's subscription page: When I click "Check", a popup opens and displays "Connection error 596: Broken pipe". Nothing conclusive in the logs, maybe anyone else...

When it comes to storage, we have been using ZFS over iSCSI in our clusters for years. Now for a couple of new projects, we require S3 compatible storage and I am unsure about the best way to handle this situation. I am tempted to use MinIO, but I've read mixed reviews about it and Ceph seems...

alright, figured it out myself. The "problem" is that I ticked "privilege separation" when I created the token. After unchecking privilege separation, everything works now as expected!

I am trying to use the terraform<->proxmox plugin and for that purpose, I have created a dedicated terraform provisioning user like this: pveum role add TerraformProv -privs "VM.Allocate VM.Clone VM.Config.CDROM VM.Config.CPU VM.Config.Cloudinit VM.Config.Disk VM.Config.HWType VM.Config.Memory...

I'm in the process of migrating our infrastructure to a more declarative, GitOps/terraform style. As a part of this, a lot of VMs will be created using customized cloud-init images (debian, fwiw). Now the only thing missing for my little puzzle is to get networking right. When creating VMs...

This is weird. What version of PVE are you using? And did you mangle with your (global) bash configuration?

It is almost 3 years now that I posted my "solution" and things have evolved a lot, since. QEMU and the linux kernel have received numerous updates, that also affect nested virtualization. Because of both performance and stability issues, we've since completely gotten rid of all Windows VMs...

HI, I need to replace a switch in one of our datacenters, that is used by a couple of PVE nodes for almost anything (corosync, ZFS over iSCSI, node to node traffic for VMs etc.). The replacement shouldn't take long, but still it may take a minute or so. For all the traffic except ZFS over...

there's actually an simple workaround for this. Say for example if your boot device that is NOT attached to the HP P420i is sda and your HP P420i devices only start at sdd, then just modify char_index from. old: char_index=({a..p}) to new char_index=({d..s}) That way, the wrapper script won't...
