Same problem for me. Regenerating the certificates did the trick, but all KVM machines must be fully stopped, and the restarted.

Mir, thanks for the link. That's exactly what I did, but I still get the same packet drop when testing with omping. BTW, the packet drop is always 56% / 10 min, on this point of view it's very stable.

I have 7 nodes that work wonderfuly from years. And suddently the switch did start dropping the multicast (56% packet loss). No recent change, no heavy load, no explenation. I've spent hours searching how to configure IGMP on this ProCurve 2920 (fw WB.16.02.0012). Documentation for 2910 is...

On a lot, but not on Procurve 1800 / 1810. Multicast is allowed out of the box, without any option. Although we can configure some limitation (1800: rate limit / 1810: storm control), that I don't recommand anyway, because many other broadcast paquets are also dropped, i.e. Bonjour. I couldn't...

I did migrate my 2 servers, and had quite a bad surprise. Corosync was failing after less than 5 minutes. After many hours of investigation, I did discover that the Procurve 1800-24G switch was the cause of the problem. A multicast test using asmping did show 25% packet loss in multicast. Those...

Spirit, I've spent the last hour to try to trigger a BSOD with crystalmark 3.0.1, but no way. It irritating not being able to reproduce what happened many times yesterday morning. Everything is working as if I did never have any problem, whatever the drivers or settings I'm using. Here are...

Yes, I found it yesterday and did upgrade my test machines. It's seems to be much more stable. I'm still testing some heavy loads, but I didn't have any BSOD with this version yet. I'm working on more tests with crystalmark to see if I can reproduce your symptom.

Hello Dietmar, I'm a bit surprised by what I've found on your wiki. You're saying you've got trouble with software raid. Soft raid is a bit more complex to configure than hardware, and I do understand your position about giving some support for it. But I don't agree with the fact that soft raid...

Thanks to all of you sharing your experience. I must specify I've started using Proxmox at the beginning of the 2.x version, last year. Previously, I was using libvirt and virtual-manager, with current kvm packages backported. By the way, thanks to Proxmox guys for your excellent job. Windows...

I've tried to migrate several Windows production servers in KVM. I've got 2 of them so unstable that I had to put them back on hardware machines. Windows has already a long list of trouble on any virtualization system (even Hyper-V), this is not new. I'm not expecting KVM of Proxmox to resolve...

You're right, I've done some changes manually. I did not have time to test it seriously yet, but I think that this issue did appear when I've changed something in the /etc/pve/openvz or /etc/pve/qemu-server symlinks, instead of working in /etc/pve/nodes. I still need to spend a couple of hours...

From this week (Dec 24), I've got several machine which got this issue while upgrading: # /etc/init.d/pve-cluster restart Syslog: Dec 24 08:56:00 elrond pmxcfs[14809]: [database] parent is not a directory (inode = 0000000000000261, parent = 0000000000000313, name = '1038.conf')...

Using Linux Mint (MGSE 12 or LMDE 2011-12) or Ubtuntu 11.10, I have the same problem when using Chromium. Firefox seems not having the same problem - although Firefox has many other trouble, including crashing 10 times per day because of Java or Flash. When using the workaround 'Show Controls'...
