Hi,
I have a group of Precision 3680 machines with Intel(R) Core(TM) i9-14900K processors.
I am creating only one Windows 10 VM on each Proxmox machine, and I am using pass-through for the disk. However, after copying a large amount of data (In the VM) to the disk, Proxmox completely freezes.
I have attached the output of journalctl when Proxmox freezes (see journalctl_crash.txt).
This issue has only occurred on 2 out of the 6 machines so far.
I noticed that in the machines without issues, the SSDs all share the same IOMMU group. In the other hand, the machines with issues have SSDs in separate IOMMU groups. Here are the screenshots for reference:
I have tried using LVM, Directory, and ZFS instead of passing through the disk, but Proxmox hangs as well.
I read forums about people with similar problems. They suggested it might be ZFS, but I was not using ZFS. Even though I was not using ZFS, I reduced the RAM and cores of the VM, but that didn't solve the problem.
I have also tried the following:
- adding `clearcpuid=600` to `GRUB_CMDLINE_LINUX_DEFAULT`
- adding `mitigations=off` to `GRUB_CMDLINE_LINUX_DEFAULT`
- installing intel-microcode
Unfortunately, none of these solutions have worked.
I appreciate any help.
