Right now I only have one VM running and disabled heartbeat, it seems to work atm. Can a faulty VM trigger this behaviour or is it heartbeat? these are the packages that are installed, i remember disabling the drbd82 package, which one should we prefer and are both version compatible? drbd.x86_64 8.0.13-1.el5.centos installed drbd82.x86_64 8.2.6-1.el5.centos installed kmod-drbd-xen.x86_64 8.0.12-1.2.6.18_92.1.6 installed kmod-drbd-xen.x86_64 8.0.13-1.2.6.18_92.1.1 installed kernel-xen.x86_64 2.6.18-92.1.13.el5 installed kernel-xen.x86_64 2.6.18-92.1.10.el5 installed kernel-xen.x86_64 2.6.18-92.1.6.el5 installed xen.x86_64 3.0.3-64.el5_2.3 installed xen-libs.x86_64 3.0.3-64.el5_2.3 installed heartbeat.x86_64 2.1.3-3.el5.centos installed heartbeat-pils.x86_64 2.1.3-3.el5.centos installed heartbeat-stonith.x86_64 2.1.3-3.el5.centos installed thx Heiko > I tried to join my kernel configuration and sysctl settings but the mail > was rejected because it was too big. > > The kernel is the one provided by CentOS, and I didn't add any conf > in /etc/sysctl.conf. > > When I unplug the dedicated network cable with some (5) Virtual Machines > launched, the reboot of both nodes is systematic.
