[SOLVED] CentOS 7 installer in Proxmox VE 5.1 crashes

[BLinux]

First time Proxmox user. Just installed VE 5.1, which went smoothly. Now, I'm trying to create a virtual machine with CentOS 7 (1611), but the anaconda installer crashes in the console.

There might a a few different problems, but this is the error message I see:

"ValueError: new value non-existent xfs filesystem is not valid as a default fs type"

Here's the VM config:

# qm config 100
bootdisk: scsi0
cores: 2
cpu: host
ide2: none,media=cdrom
keyboard: en-us
memory: 1024
name: testvm1
net0: virtio=0E:7C:B0:4B:5A:08,bridge=vmbr0
numa: 0
ostype: l26
scsi0: vmimages:vm-100-disk-1,size=16G
scsihw: virtio-scsi-pci
smbios1: uuid=305972c7-cc77-4eee-8d75-0440ae3d3ae0
sockets: 1
tablet: 0
vga: qxl

what is causing this?

Hi,

First time Proxmox user. Just installed VE 5.1, which went smoothly. Now, I'm trying to create a virtual machine with CentOS 7 (1611), but the anaconda installer crashes in the console.

This sounds like an outside cause - not related to PVE directly. Searching after your error allows to find a few entries, e.g.:
https://bugzilla.redhat.com/show_bug.cgi?id=1169034
They suggest that the kernel and initrd do not match, where did you get this image?
Try redownloading an official known-good image, I re-tested just now and could successfully install CentOS 7 on PVE 5.1 using XFS.
Else maybe try a fedora installation too? It also uses the anaconda installer and has a similar (but newer) base than CentOS.

Looks like you're using PXE (no ISO attached)...Thomas is right, this misleading message is due to pxe-booted kernel and initrd does not match the anaconda installer.

Indeed, I was booting off our PXE boot system that is used by other virtualization hosts to install OSes. I'll look into the PXE system to see if there is a problem; but the last time I used it to install CentOS 7 on another KVM host, it was working just fine.

anyway, thank you guys very much for pointing me into a direction I hadn't considered.

just wanted to report back that indeed the PXE boot system was broken temporarily. there was an update to CentOS 7.4 that didn't complete properly causing the issue above. had absolutely nothing to do with Proxmox.

thank you guys for your help in pointing me in that direction.
