Hi Neal and Soren, I'm replying on Paolo's behalf, first of all thanks for your attention and sorry for our late reply but we've been experimenting different things to resolve or detect the real problem we're experiencing.
We are running hardy with a livbirt + kvm setup on a 8 CPUs machine with 16 GB RAM, we're using different guests operating system, some newly installed (hardy jeos), two directly ported from our old qemu setup (running dapper), a winxppro machine and a centos 5 guest ported from a vmware image. Shortly after porting our new setup to kvm we started noticing some issues with the old dapper machine running the zabbix monitoring system, periodically (60 minutes circa) the network was going down, we noticed this by looking at zabbix cpu utilization graphs presenting periodically gaps of about 15 minutes, we also noticed some network problems with the other machines but we've not been able to reproduce them programmatically, the centos machine (running trixbox) sometimes requires a networking restart to come back to work... Our problems seems pretty similar (but not identical) to the ones described here: https://bugs.launchpad.net/ubuntu/+source/kvm/+bug/194304 http://thread.gmane.org/gmane.comp.emulators.kvm.devel/13537 ATM we are running kvm-68 on hardy, I've backported Soren's intrepid package to hardy, basically nothing changed with kvm-68 just the fact that we're not seeing the dmesg error anymore (so I'm wondering if the dmesg error and the problem are really related), today I've finally found a working combination for the zabbix guest, I've ported it to run on a jeos machine with virtio as network device and it seems to be working properly (until now). I'm going to attach the information Neal requested, regarding dmesg entire error and registers, the error posted by Paolo is everything we've found repeated on our dmesg, no other information were reported there by kvm. We'll promptly report back with additional informations as we found them. Thanks again for your attention. ** Attachment added: "uname-a.log" http://launchpadlibrarian.net/14515491/uname-a.log -- kvm network instability https://bugs.launchpad.net/bugs/228163 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
