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: (XEN) Std.
