Forgive the top posting.
I have had very similar issues in a very similar scenario. I have
searched the web for a solution and asked here to no avail.
I had about 8 virtual servers running Xen on 2 host machines at one
point but because of this issue have reduced it to 4, moving the others
to VMWare images until I can sort out what I've done wrong that would
create this problem. I also cannot install new file based domU's, they
also hang mid-install.
If anyone out there knows what can cause this, I'd love to hear about
it. My servers are all CentOS 5 based running a 2.6.18-53.1.14.el5xen
i686 kernel.
