I have a very similar problem as well-- I see hangs under the same conditions (high disk activity in domU), but my domU *is* on a zvol. My setup is almost identical to Maurice's, except I give 4G to dom0, and as I mentioned, my domU is on a zvol. In my case, I see the hang when running a big imapsync job. My domU is running CentOS 5 and Zimbra. My dom0 is not used for anything other than management. I was thinking this was hardware related, but it has happened on different physical servers that are both brand-new X4150s. It happens with both snv_89 and snv_90. I'd love to figure out what's going on here-- this has stalled my project. Thanks, Eric _______________________________________________ xen-discuss mailing list [email protected]
