[SOLVED] Kernel panic installing rocky or almalinux

[fabian]

so right now almalinux 9 still cant running under cpu-type kvm64 ?
it should be set to host ?

no, see the docs:

https://pve.proxmox.com/pve-docs/chapter-qm.html#_cpu_type

The backend default is kvm64 which works on essentially all x86_64 host CPUs and the UI default when creating a new VM is x86-64-v2-AES, which requires a host CPU starting from Westmere for Intel or at least a fourth generation Opteron for AMD.

no, see the docs:

https://pve.proxmox.com/pve-docs/chapter-qm.html#_cpu_type

so there is no possible solution OS almalinux 9 with cpu type: kvm64 ?
in the first page.. the solution is set cpu-type into "host". which i need "kvm64" obviously.

you cannot use kvm64, since that doesn't have all the features that that distro requires.. you need to use a CPU type that does (either one of the physical ones matching your CPU, or host, or the "bumped baseline" x86-64-v2-AES). please read the docs, they explain it in more detail.

You could do 'host' (which would also give you more performance) or in the Proxmox 8.x series, you could use the new default of 'x86-64-v2-AES' which gives you greater compatibility of Proxmox features (like Live-migration) when it comes to having different servers with different cpu generations all in the same cluster.

I hope that was helpful!

As fabian mention you can use:
- Intel Nahelem
- Amd Opteron gen4
- or just use Host

Out of interest, just tried the same KVM installation with Rocky Linux 10 (RHEL 10) and it seems that host doesn't work on my hardware. Has anyone had any luck installing RHEL 10 on their PMVE?
