[Qemu-devel] [Bug 816860] [NEW] Guest machine freezes when NFS mount goes offline

[Igor Blanco]

Public bug reported:

I have a virtual KVM machine that has 2 CDROM units with ISOs mounted
from a NFS mount point. When NFS server goes offline the virtual machine
blocks completely instead of throwing read errors for the CDROM device.

Host: Proxmox VE 1.8-11 (Debian GNU/Linux 5.0)
KVM commandline version: QEMU emulator version 0.14.1 (qemu-kvm-devel)
Guest: Windows 7 professional SP 1
