Hi,
may be somebody has seen similiar crashes in the past and/or any solution?
This is a NetBSD:
NetBSD xxxxxxxxxx 6.1.5 NetBSD 6.1.5 (XEN3_DOMU) amd64
running as PV DomU under XEN with a Linux Dom0.
It seems the system is running stable with just one Xen cpu pool.
After dividing the two "stone" machine by xen cpupool-numa-split and assigning
the DomU to the second resulting cpupool the systems seems to get instable
after a "while" (hours).
I'm not shure if it is related to the cpupool mechanics - so i brought the xen
HV back to the "initial" state with the one default cpupool Pool0 and see what
get happen in the next...
...some thin meat for the coders:
