Summary: Guest domains dying and resurrecting
Product: Xen
Version: unstable
Platform: x86
OS/Version: Linux
Status: NEW
Severity: normal

I am seeing guest domains die and resurrect. This is happening on a non-
PAE x86 SLES 9 SP2 build, using the following changeset:

summary: Merged.
Machine: IBM xSeries 235, 1GB RAM, SCSI drives.
This is what ''xm list'' shows initially:
Name ID Mem(MiB) CPU VCPUs State Time(s)
Domain-0 0 120 0 1 r----- 899.8
vm1 1 127 1 1 -b---- 684.8
vm2 2 127 1 1 -b---- 555.7
Later on, the domain IDs have incremented. I have neither manually
stopped nor started any guest domains:
Name ID Mem(MiB) CPU VCPUs State Time(s)
Domain-0 0 121 0 1 r----- 1171.5
vm1 3 126 1 1 -b---- 163.4
vm2 5 126 1 1 -b---- 11.0

Re: [Xen-devel] Guest domains dying and resurrecting
Thanks for the reply. My concern is why the domains are crashing. I''ll try to get more detail, as I saw the same situation this morning on the same machine.
