Hey folks, We''re unable to find netfront driver support in newer kernels and have been forced to use the 2.6.18 kernel from centos. Is there a solution to this? Is there any chance that the kernel updates from the XenSource tree will be merged into mainline? Maybe a git branch?

It''s called xen-netfront. -- Fajar _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Oops. Sorry for the ambiguity. We need the hvm flavor of netfront. Sent from my PDP-11 On Oct 15, 2009 12:33 AM, "Fajar A.

Novell has forward-port to 2.6.27 kernel, it''s included in SLES11 and possibly in OpenSUSE (not sure about OpenSUSE). Also I think Redhat guys are working on porting PV-on-HVM drivers to upstream Linux pv_ops framework, so then they''d work with any upstream Linux kernels (once included upstream). I think they''ll working on porting them to 2.6.31 pv_ops kernel. Now the question is why you don''t use PV linux guests? PV guests are most probably faster and you have PV drivers automatically there.. -- Pasi> Sent from my PDP-11 > > On Oct 15, 2009 12:33 AM, "Fajar A.

If you''re concern about pygrub''s security (since it loads some files from domU and put it on dom0), there''s also pv-grub (might require newer Xen version though). -- Fajar _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
