Hello Xin.
In our case, the disk I/O load was always in the DomU (via a
passthrough block device from Dom0), and was always associated with
high network traffic, as our SAN is ethernet attached (AoE, not iSCSI).
We can crash the system through DomU disk I/O and associated network
traffic alone. Accessing /proc/slabinfo greatly exacerbated the problem.
P.S. You're missing 'cat' in the script your showed:
!#/bin/sh
while [ 1 ] do
cat /proc/slabinfo >> ./slabinfo.txt
end
Hi,
Did you find a solution?
I have the same problem when transfering large files too, I am testing
with selinux off and it seems so far not to crash.
My dom0 and domU are all CentOs 5 which runs Xen 3.03 from the distro.
Also, I use aoe and I changed the defaulf network interface used by the
aoe instantiator from
aoe-stat e9.0 10.737GB xenbr0,eth1,eth0 up
to
aoe-stat e9.0 10.737GB eth1 up
So far it seems to have fixed the crashes.
What have you done to fix the issue ?
Regards,
