Hi, I''m trying to use a linux HVM guest (DomU) with Paravirtual drivers for network and disk access on my updated Fedora 8 setup. In order to achieve this, I''ve downloaded the source package of appropriate (same version) Xen Hypervisor from redhat website, then copied this source to my DomU and compiled the unmodified_drivers folder following the steps mentioned in the README file. Everything went fine and I got my xen-platform-pci, xen-baloon, xen-vnif and xen-vbd (.ko) drivers. They modprobe fine, however, after some time, the DomU freezes up. Specifically, system freezes quicker (usually) with only vbd, and takes more time to free with only xen-vnif loaded into memory. When I say only, xen-platform-pci always loaded, but only the mentioned driver is netfront or block-front, others are ioemu. xen-vnif also complains about a memory leak when it''s rmmod ''ed. Shall I file a bug report? Thanks, Emre Erenoglu erenoglu@gmail.com
