Hrm... thou I'm not using XenServer. The weird thing is, that it is working for a older version of xen.I might should point out, that the 4.0.1-rc3 box is running debian, and the 3.3.1 one is running centOS. Also, I noticed following output in the messages file over night:Aug 4 18:53:54 dhclient: No working leases in persistent database - sleeping. Aug 4 19:00:35 dhclient: send_packet: No buffer space available Aug 4 19:00:45 dhclient: send_packet: No buffer space available Aug 4 19:00:53 dhclient: send_packet: No buffer space available Aug 4 19:01:02 dhclient: send_packet: No buffer space available Aug 4 19:01:15 dhclient: send_packet: No buffer space availableMay that indeed have something to do with the network drivers included in pv_ops? Are there some greater differences between the ones in pv_op and xen-2.6.18? It could be completely unrelated, but it's known that NetBSD domUs are broken under XenServer. This is due to NetBSD using 'flipping' mode in its network driver instead of 'copying' mode: http://mail-index.netbsd.org/port-xen/2010/06/15/msg006105.html -Dustin On Wed, Aug 4, 2010 at 5:29 AM, Christopher R. K.<Feuerball_@xxxxxxx> wrote:Hello. I recently tried installing NetBSD-5 on xen-4.0.1-rc5, which resulted in no network (xennet0 can't get IPs per dhclient and has no connectivity if set by hand). Tried it with netBSD-5.1-RC3-1 i386 PAE& amd64, netBSD-5.0 and even 4, all with the same result. On a older xen version (3.3.1) networking works fine, so I assume it's a xen bug, and not a netBSD-kernel one. One server has a pv_ops kernel for Dom0, the other not. A debian test-VM can get a IP just fine per DHCP and connect to the internet.
