Re: does anyone have Xen running on an AMD system?
Do you use stock Xen or the Debian bundled one? However I'd suggest that boot from local disk (usb is also good) and use nfs only for guests. I'd also suggest that try 3.4.3. If you could boot CURRENT and 8-RC2 on that, at least try it, it would help a little imho. Martin Cracauer wrote: FWIW, I have a Xen 4.x install on a Phenom II now and I can give out accounts on there if it helps the cause. BTW, did anyone succeed in making a Xen 4.x install with a Debian/squeeze dom0 go through a diskless PXE boot? I can't use the same kernel that works on local disk since it doesn't have root_nfs. All my attempts to compile that very kernel with Debian's own config and sources ends up with the screen goes blank after Xen messages when entering dom0 kernel syndrome which indicates to me I am missing some Dom0 support in that kernel. But the precompiled one works. Also, previously I had problems that the Xen scripts connecting the DomU via an Ethernet bridge would intermittently disconnect the physical Ethernet connection. Which in the case of a diskless machine stopped that very script ;-) Anyone got any tips here? Not use Debian would be a way I suppose. What do you guys have for Dom0?

Re: does anyone have Xen running on an AMD system?
Sory my bad i will atache path to curent and tomorow i will test it. Tobiasz In current patch is attached to file i386/i386/machdep.c. There is no line #if defined(XEN_PRIVILEGED).

Re: does anyone have Xen running on an AMD system?
I know there's no problem with simple HVM, so I'll compile a PV kernel and check it. (I hope at least.) Colin Percival wrote: Oops... I should have been a bit more specific. The problem is when running paravirtualized, not via HVM, so the standard install disk won't help. On 01/11/11 11:18, Gót András wrote: I'll try to fire up a VPS on an Opteron 2376 soon.
