I installed a VM under Proxmox 5.0.5 running CentOS 7 (Kernel 3.10.0-514.26.1.el7.x86_64).
The virtual machine boots fine, but when performing a reboot (just the command 'reboot' from SSH), it never boots. It hangs at this message:
"smpboot: CPU0: Intel QEMU Virtual CPU version 2.5+ (fam: 06, model: 06, stepping: 03)"
What could be the reason or how can I debug this further?
