Re: [Xen-users] 2.6.31 xenified kernel - not ready for production

[Sassy Natan <sassyn@xxxxxxxxx>]

I have built 2.6.31-5 + Xen (old style) + Ubuntu patches for ubuntu 9.10 Seems to work fine for 1 week now

 

I have problem but with the pvusb - still I dont know how to use it.

 

If u want I can put the deb files in some ftp servers

Hmm.. dunno if this helps, it's from a user (from #xen) having problems with the
