http://bugzilla.novell.com/show_bug.cgi?id=574325 http://bugzilla.novell.com/show_bug.cgi?id=574325#c0 Summary: network freeze at domU reboot/shutdown Classification: openSUSE Product: openSUSE 11.2 Version: Final Platform: x86-64 OS/Version: openSUSE 11.2 Status: NEW Severity: Major Priority: P5 - None Component: Xen AssignedTo: jdouglas@novell.com ReportedBy: diablo@iasi.roedu.net QAContact: qa@suse.de Found By: --- Blocker: --- Created an attachment (id=339127) --> (http://bugzilla.novell.com/attachment.cgi?id=339127) domU xen config User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.1.8pre) Gecko/20100123 Ubuntu/9.10 (karmic) Firefox/3.5.7 I installed OpenSuSE 11.2 in dom0 and one virtual machine (OpenSuSE 11.2) as domU using the configuration attached. When I shutdown (or reboot) the virtual machine, dom0 networking just stops working for around 30 seconds. After that, the dom0 starts to work again, as expected. One very peculiar thing is that that packets are received by dom0 (tested on a blade system, connected remote on management console and using tcpdump) but nothing "leaves" the server. The network stops working in the exact moment that the virtual server stops. Reproducible: Sometimes Steps to Reproduce: 1.install & boot with xen enabled kernel in dom0 2.install OpenSuSE 11.2 in domU 3.on domU, shutdown -r now Actual Results: The network on dom0 stops sending packets on the network Expected Results: send packets on the network. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I tried using both emulated RealTek 8139 and e1000. Can you try the 8139 and see if same problem exists? E.g. change vif config to vif=[ 'mac=00:16:3E:55:34:91,bridge=br0,model=rtl8139', ] BTW, since the domU os is 11.2 why not use the pv version? -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
