Description Chao Yang 2012-03-31 12:44:33 UTC 
Description of problem:
I have 3 hosts running in the same cluster:
dhcp-72-66-intel,  SPM
intel-e5620-16-6.englab.nay.redhat.com
intel-e5620-16-5.englab.nay.redhat.com

And dhcp-72-66-intel was in SPM status. I found all VMs running on intel-e5620-16-6.englab.nay.redhat.com have been in unknown status, from the Events tab, I see "Error: Network error during communication with the Host." So, I login to the host, ping got replied from remote host. Not sure why it complained this error. After a while, dhcp-72-66-intel and intel-e5620-16-6.englab.nay.redhat.com were set to up in "Hosts" tab, all seems right, except that: 
1.SPM changed to intel-e5620-16-6.englab.nay.redhat.com
2.VMs running on intel-e5620-16-6.englab.nay.redhat.com were shutdown, I need to start them up.

Version-Release number of selected component (if applicable):
# uname -r;rpm -q qemu-kvm libvirt vdsm
2.6.32-220.el6.x86_64

what you describe fits to a temporary loss of network connectivity to the spm host. I do not see shred of a vdsm bug. Please reopen if this reproduces, but try to understand when it happens.
