Subject: Re: [Xen-devel] disk offline with xen4.0+pvops188.8.131.52
To: Jeremy Fitzhardinge <jeremy@xxxxxxxx
Hi, I'm a friend of yingbin wang,
we take some pictures for the disk offline, in the attachment.
We did many stress test, the result is:
disk offline disappears when there is no xen hypervision in 184.108.40.206,
when we use RHEL 5.x kernel+Xen, disk offline disappears too. It seems that redhat should add some patch to solve this problem..
disk offline appears on:
linux-220.127.116.11 + Xen-3.4.2
linux-18.104.22.168 + Xen-4.0.0
linux-22.214.171.124 + Xen-3.4.2
Fedora linux-2.6.32 + Xen-4.0.0
Suse linux-126.96.36.199 + Xen-3.4.2
The servers tested above are all with Nehalem architecture CPU.

What do you mean by "disk offline"? Are there some specific messages on
the kernel console?
