Subject: an issue with 'xm save'
Date: Fri, 21 Sep 2012 17:41:27 +0800 [thread overview]
Message-ID: <505C3647.1030003@oracle.com> (raw)
Hi maintainers,
I found there is an issue when 'xm save' a pvm guest. See below:
When I do save then restore once, CPU(%) in xentop showed around 99%.
When I do that second time, CPU(%) showed 199%
top in dom0 showed:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
20946 root 18 -2 10984 1284 964 S 19.8 0.3 0:48.93 block
4939 root 18 -2 10984 1288 964 S 19.5 0.3 1:34.68 block
I could kill the block process, then all look normal again.
xen and xen-tools are both generated with xen-unstable.
I tried xl, but it segfault.
I also tried ovm3.1.1(xen-4.1.2-18.el5.1 and xen-tools-4.1.2-18.el5.1),
can't reproduce.
Did anybody see similar issue before? Any fix already there?
thanks
zduan
