KVM is in "boot loop"

[KiX]

Hi Proxmoxer,

I also opened a topic on the OPNsense forum, but I want also to discuss this issue here.

I'm using the latest Proxmox VE on my "HP ProLiant Microserver N40L" and my KVM is looping during the bootup process and I can't figure it out how I can deeper inspect this issue, so I need your help please!
The strange thing is, the 32bit version of OPNsense is working and the 64bit version is also working but only with "KVM hardware virtualization" disabled, and this of course extremly slow

Here is a screen record of a default kvm64 which is booting up OPNsense 64bit (OPNsense-19.1.4-OpenSSL-dvd-amd64.iso):

On the OPNsense forum, I also opened a topic, but I can't link it because of my new forum user :/

Thanks guys!

Oh, and btw, in syslog it's showing:

pve01 kernel: [  284.573818] SVM: KVM: Guest triggered AMD Erratum 383

 

[dcsapak]

maybe this helps:

Hi dcsapak,

thanks for your Input!
I tried the „Solution“/workaround but it didnt worked.
Looks like the CPU isn‘t compatible with FreeBSD Kernel? :-(

I have the same problem.

When I try to installI OPNsense 20.7 in Proxmox 6.2-10. It restarts and in /var/log/syslog in Proxmox, appears: SVM: KVM: Guest triggered AMD Erratum 383.

The same thing happens to me with OPNsense 20.1.

I have Proxmox 6.2-10 on a HPE ProLiant MicroServer, with an AMD Turion II Neo N54L Dual-Core processor, 6 GB of RAM and 250 GB of disk.

I create the VM using 1 processor core, 1 GB of RAM and 10 GB of disk.

I tried: Change CPU Type kmv64 to qemu64; test with UEFI BIOS (and create partition) instead of SeaBIOS; SCSI and IDE disk; i440fx and q35 machine; install amd64-microcode. I even reinstalled Proxmox to test with version 6.2-4, but none of this worked.

Any solution ideas?
