[RHEV] Abnormal vm stop device virtio0 Input/output error in RHEV Manager.

Solution Unverified - Updated -

Issue

  • A test RHEL 3 virtual machine (VM) paused with the following virtio driver error via the QEMu monitor. The general time period is one where NFS shared storage latency might be increased, but this has not been a problem previously while this particular guest was running under libvirt KVM. How to figure out what caused this, and if a guest becomes paused what to do?
