100% iowait in domU with no IO tasks.
...0
I check other domU and dom0 on same server - there were high iowait: from 20% to 50% with few transactions per second and about 0.1-1.5 Mb/sec storage bandwith usage per domU. This domU have no disk IO at all but show LA 15 and possible higher.
We have 6 domU on 8-core server with 7 FUJITSU MBB2147RC SAS HDD on DELL PERC 5/i RAID controller.
CentOS 5
Xen 3.1.0
Kernel 2.6.21
We suffer from this problem for a while on many our xen hosts, it is not a single-time issue.
