    Windows 10 VM So Slow when cpu type is host

    Windows 10 VM is too slow on Proxmox. Even dragging the window is too slow. I have two VMs with similar settings. But the second VM is not slow. The difference is, slow VM's cpu type is host , while fast VM's cpu type is qemu64 . VM1: agent: 1 balloon: 0 bios: ovmf boot...

    IO is slow on the VM, but fast on the host.

    The physical disks are NVMe and provisioned with lvmthin. Very fast when benchmarking a thin-volume assigned to a vm on host . But in vm it is quite slow. Please advise for DISK IO performance. VM Options: ``` -drive...

    avx2 cause kernel panic

    cpu-models.conf: cpu-model: avx flags +avx;+avx2 phys-bits host hidden 0 hv-vendor-id proxmox reported-model kvm64 Adding the avx2 option causes a kernel panic. Both Ubuntu 20.04 & 22.04 are the same. Is there a bug in qemu?

    Feature Suggestion: AVX/AVX2 CPU flags

    We can change the CPU to host to use AVX, but live migration is difficult in this case. AVX is supported by most server CPUs. Like aes, it would be nice to be able to use AVX while using kvm64. Example) AVX is required from MongoDB version 5 or later.

    The VM dies with no logs.

    There is no sign of shutdown even inside the VM, and it was forced to stop. Both syslog/kern have no logs. Any way to find out the cause? Surely it will be again. version: pve-manager/7.1-7/df5740ad (running kernel: 5.13.19-2-pve)

    notice: RRDC/RRD update error

    Not all methods on the forum work. 1. NTP Sync (Now, all nodes synced < 100ms) 2. systemctl stop rrdcached; rm -rf /var/lib/rrdcached/db; systemctl start rrdcached; systemctl restart pve-cluster 3. The rtc clock is also synchronized. What's strange is that nodes that are itselves are marked...

    During pci passthrough, the VM does not start with qm, but it can with run /usr/bin/kvm.

    Running the qm start command or from the GUI throws a `got timeout` error and the VM does not start. However, if run the following command directly in the shell, it will work. ``` /usr/bin/kvm -id 1003 -name pc-01 -no-shutdown -chardev...

    Are there any plans to support virgl?

    I want to take acceleration of graphics acceleration using virtio-gpu. By the way, proxmox's qemu doesn't seem to support virgl. Are there any plans to apply? Is it because it still doesn't support virgl over network? Where can I find information on this? Or is there a way to implement it in...

    Can use SRV TCP Record at PVE RBD Storage?

    Hello, https://pve.proxmox.com/wiki/Storage:_RBD Here's only monhost in the description. https://docs.ceph.com/en/latest/rados/configuration/mon-lookup-dns/ If look here, ceph supports srv record. Can I use srv record in proxmox too?
