I¹m running SXCE b87 on a couple of Dells in an xVM cluster, and I just experienced this dom0 panic:

The dom0 network interfaces include onboard bnx and an add-in e1000 (Intel 1000-PT). DomUs that were running at the time: * about a dozen 64bit paravirt Ubuntu Hardy (8.04) domU guests running with the XenSource 2.4.18 vmlinuz kernel from the Xen 3.1 x86_64 binary tarball * one SXCE b85 paravirt domU The guests were all idle. Primarily playground/development guests with nobody using them at the time. Of the 32G of memory, only 12G was in use by those guests at the time, the dom0 still had 19G of memory unallocated (balloon). The domUs are all running on iSCSI devices exposed by the dom0¹s initiator, as exposed from another Dell 2970 acting as an iSCSI server (zfs zvols, iscsishare=on). This is all in a lab, of course, none of this is production. Perhaps a b90 upgrade is in order. I¹m willing to give just about anything a try. - Ian C. Blenke <[EMAIL PROTECTED]> <[EMAIL PROTECTED]>
