profiling KVM i/o on CentOS 5
Hi,
I am wondering what tools are available to troubleshoot KVM I/O problems on
CentOS 5, given that the kernel is 2.6.18 with some backports to support
virtualisation?
kvm_stat / kvmtrace - These seem to be available in the kvm-tools package.
ftrace related things seem not to be available.
OProfile is available, can it be used?
Also, SystemTap is available, can it be used?
Anything
