grub

Hello, we are using a old, mostly unused Proxmox server (HP ProLiant DL160 Gen8) as backup/fail-safe Hypervisor for our infrastructure production VMs. I boot up that server ever week and clone the storage of those VMs via "zfs send" to it. Now it seems that one disk is broken and it does not...

Hi all, I tried moving a Centos 6 VM from Citrix XenServer v6.5 to Proxmox v7.1-10, but the VM is getting stuck after the GRUB menu. I regenerated initramfs, but the VM is still hanging. I also tried removing the "quiet" kernel options, but that didn't help (not pictured here). It boots fine...
