[Xen-devel] Big network problem on recent kernel update from xen/stable2.6.32.x
I see only today how with last build of kernel do from last commit (27ed1b0e0dae5f1d5da5c76451bc84cb529128bd) do network of windows xp domU with gplpv 0.11.0.213 unusable, ping lost or over 1 second unable to connect with rdp to domU, unable to use network from domU and viceversa Also with build with 2.6.32.14 (from commit e8734951b7a8d838050277696541a7e57183bdce) have problem but my last build with 2.6.32.13 not have network problem, I can not remember committing but i have build on 26 may if just remember All these build have same config: http://old.nabble.com/file/p28805128/config-2.6.32.15 config -- View this message in context: http://old.nabble.com/Big-network-problem-on-recent-kernel-update-from-xen-stable2.6.32.x-tp28805128p28805128.html Sent from the Xen - Dev mailing list archive at Nabble.com. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

RE: [Xen-devel] Big network problem on recent kernel update fromxen/stable2.6.32.x
I discovered the same issue, with PV drivers only. On Xen 3.4.3 and 4.0.0, I experienced the same problems. Using one fully HVM linux domu, and fully PV linux domu, and one windows domu with gplpv drivers, I tested a 2.6.32.13 build from two weeks ago, and a 2.6.32.15 build from Saturday with the same config. PV network does not work properly with 2.6.32.15, but qemu emulated device in the HVM domain without PV drivers works fine. All three work just fine with 2.6.32.13. Symptom is that packets never seem to get back to the domu. For example, I have VMs on 192.168.2.0/24 subnet, and dom0 routes traffic to local physical net on 192.168.1.0/24. If I ping 192.168.1.1 from a domu with PV drivers, I can see the echo request and reply in tcpdump on the bridge device on dom0, but domu does not seem to see the reply. In some other cases, domu sees the reply, but reports 999-1001ms response times, which I know are inaccurate by watching tcpdump output. Traffic other than ICMP is completely unreliable; the packets that do get through have incredibly high latency. I''m 100% sure I don''t have iptables or other network config problems. -----Original Message----- From: xen-devel-bounces@lists.xensource.com [mailto:xen-devel-bounces@lists.xensource.com] On Behalf Of Fantu Sent: Monday, June 07, 2010 9:20 AM To: xen-devel@lists.xensource.com Subject: [Xen-devel] Big network problem on recent kernel update fromxen/stable2.6.32.x I see only today how with last build of kernel do from last commit (27ed1b0e0dae5f1d5da5c76451bc84cb529128bd) do network of windows xp domU with gplpv 0.11.0.213 unusable, ping lost or over 1 second unable to connect with rdp to domU, unable to use network from domU and viceversa Also with build with 2.6.32.14 (from commit e8734951b7a8d838050277696541a7e57183bdce) have problem but my last build with 2.6.32.13 not have network problem, I can not remember committing but i have build on 26 may if just remember All these build have same config: http://old.nabble.com/file/p28805128/config-2.6.32.15 config -- View this message in context: http://old.nabble.com/Big-network-problem-on-recent-kernel-update-from-x en-stable2.6.32.x-tp28805128p28805128.html Sent from the Xen - Dev mailing list archive at Nabble.com. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

RE: [Xen-devel] Big network problem on recent kernel updatefromxen/stable2.6.32.x
I don''t use the xend scripts to create a bridge, I use fedora/red hat config scripts to create the bridge at boot. I use a bridge called xenbr0 that has no physical interface, but it does have an IP assigned in dom0, which handles routing for now. -----Original Message----- From: xen-devel-bounces@lists.xensource.com [mailto:xen-devel-bounces@lists.xensource.com] On Behalf Of Pasi Kärkkäinen Sent: Monday, June 07, 2010 11:04 AM To: djmagee@mageenet.net Cc: Jeremy Fitzhardinge; xen-devel@lists.xensource.com; Fantu Subject: Re: [Xen-devel] Big network problem on recent kernel updatefromxen/stable2.6.32.x On Mon, Jun 07, 2010 at 09:53:09AM -0400, djmagee@mageenet.net wrote:> I discovered the same issue, with PV drivers only.

i rebuild from commit 930edab1aba24f1807fd9ab8127006115bbd3422 and network work, i think how the network problem was introduced by this commit: commit 528ea798f02ccb03023e72cbda665ed5c3eec6b1 Merge branch ''xen/dom0/backend/netback-tasklet'' into xen/next * xen/dom0/backend/netback-tasklet: xen/netback: Use Kernel thread to replace the tasklet. xen/netback: Multiple tasklets support. xen/netback: Introduce a new struct type page_ext. xen/netback: Move global/static variables into struct xen_netbk. Maybe some problem with new commit not see in xen/next but see in xen/stable because in xen/stable there are merging of 2.6.32.x upstream and in xen/next no, there are some differences between xen/next and xen/stable who cause some unexpected behaviours Fantu wrote:> > I see only today how with last build of kernel do from last commit > (27ed1b0e0dae5f1d5da5c76451bc84cb529128bd) do network of windows xp domU > with gplpv 0.11.0.213 unusable, ping lost or over 1 second unable to > connect with rdp to domU, unable to use network from domU and viceversa > Also with build with 2.6.32.14 (from commit > e8734951b7a8d838050277696541a7e57183bdce) have problem > but my last build with 2.6.32.13 not have network problem, I can not > remember committing but i have build on 26 may if just remember > All these build have same config: > http://old.nabble.com/file/p28805128/config-2.6.32.15 config >-- View this message in context: http://old.nabble.com/Big-network-problem-on-recent-kernel-update-from-xen-stable2.6.32.x-tp28805128p28831366.html Sent from the Xen - Dev mailing list archive at Nabble.com. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
