Hi,
have you tried to pin your vCPU's to dedicated Cores?
It might be suboptimal if a domU uses.. say core 0 of
cpu 0 and core 0 of cpu 1 ... or anything not on the
same cpu.
config:
e.g. use the second cpu on a 2x dualcore system
count starts at 0.
cpus = [ 2,3 ]
If your domU is bridged, you might try to disable
transmission checksums on the NIC's.
ethtool -K [nicname] tx off
Anyway, you mentioned high I/O latency due to network
issues. Is your domU using some kind of NFS or something?
Btw. I might missed this part, but are you using PV or
HVM guests?
Greetings
