I'm using an ubuntu hardy dom0 with kernel version 2.6.24 and xen version 3.4.0, I'm running an opensolaris 2009.6 pv domU. The opensolaris domU is a NFS server, of which my ubuntu dom0 is a client. However the IP layer somehow keeps failing, causing any application on the dom0 to freeze. If I switch to the console of the opensolaris domU and issue a ping to the dom0, this also fails. After a while (not sure how long), the network resumes operation.
I've tried ping flooding the solaris guest, and also copying large files over cifs, but it doesn't seem to cause the same problem. It's quite intermittent. I'm not sure where to look on the solaris side of things to find any error logs to help diagnose the problem. Can anyone help with this? -- Michael -- This message posted from opensolaris.org
