Hi all,
I had installed the Xen 3.0.3 on a opensuse 10.2 (64 bits) on new
quadcore intel processors with VT support, on a Dell Power Edge 1955
blade. I had many machines working. This installation had a poor network
performance when using hardware virtualization. My applications for MPI
require low network latencies.
I try to upgrade to Xen 3,0.4 to check the network performance.
I downloaded the tarball, and I installed it.
Now my machines doesn''t run. Aditionally at the secont xm related
comand
used the dom0 crashs.
I ask previously for help at xen-users, there they recommend me the
xen-devel list.
Any help is welcomed
regards, cesar
Last lines of xm dmesg say:
