Short story: Would it be possible to get kernel-debuginfo-2.6.9-67.0.20.EL.x86_64.rpm on di.c.o? I have a need to run crash on a 2.6.9-67.0.20.ELxenU xm dump-core. Long story: Two Dell 6950 (now called R905, 4 Dual-Core AMD Opteron 8200 series) heartbeat/drbd nodes running the stock CentOS 5.2 Dom0. The domU's are the only resources in heartbeat. Dom1 is a perfectly running, updated, CentOS 5.2 Apache/MySQL/Samba server (2.6.18-92.1.6.el5x...

...es because of the xenU kernel I didn't think about. I forgot to exclude rpm database and /lib/modules. Because the synced rpm database doesn't include the xenU kernel anymore I installed the latest one again. I got this warning: WARNING: No module ata_piix found for kernel 2.6.9-67.0.22.ELxenU, continuing anyway Looking around I don't have this module for the old kernel (2.6.9-67) either. But it's referenced in modprobe.conf. Nevertheless, I could boot the VM. A locate shows this module in all non-xenU kernels under /lib/modules, sometimes in a scsi, sometimes in an ata subd...

Hi all, I'm having issue with my Centos 5.1 /Xen installation. I'm having 2 dom0 running 2.6.18-53.1.4.el5xen (x86_64). These two dom0 are connected to a SAN. These two dom0 hosts multiple domU like Centos 4.5 (2.6.9-55.0.9.ELxenU) and Centos 5.1 (2.6.18-53.1.4.el5xen). These two dom0 run ntpd to synchronize dom0 time. When i start a virtual machine on the first dom0 all seems good, the domU time is like the dom0 time. The problem appears when i migrate the domU to another dom0. After the migration, the time in domU on the...
