I have done a bit more testing and this also happens with a manually
compiled DRBD 8.4.5 and manually compiled drbdsetup, so this bug is
probably more something for the DRBD developers to fix. I will address
this issue on their mailinglist.

When you use the same resource for 2 minors, it crashes the kernel. Of
course you should not do that, though I think it should not crash the
kernel. The expected output is just an error message. This makes DRBD
resource/minor management more difficult and also kind of dangerou
After some testing, I have found a possible cause. The instance with SMP
and CentOS i386 seems to boot fine when using a different clocksource.
You can test this by booting the CD/DVD image with: linux
clocksource=acpi_pm
I have tested the KVM clocksource and the acpi_pm clocksource several
times
If I boot from the ISO "CentOS-5.5-i386-bin-DVD.iso" from the CentOS
FTP, the instance will hang at the same point as booting the instance
from the virtual disk. It is solved by disabling SMP (using just 1 CPU).
This is my KVM commandline:
kvm -daemonize -enable-kvm -smp 8 -smp 8,cores=4 -m 2048 -
One of the virtual machines with 2 GB RAM, is already using 3.5 GB RAM
here, so the leaking still exists. I hoped that this was the fix...
Has anyone already tested qemu 0.12.4? If this didn't fix it, the bug
might still exist in the new qemu version.

Thanks for the patch :)
I've installed the patched version on two production nodes here. I will
have the results in a few days probably.

They are doing different things, but mostly webserving tasks.
The strange thing is, one of the virtual servers is running an

Public bug reported:
Binary package hint: qemu-kvm
Ubuntu release: 10.04 LTS
Package version: 0.12.3+noroms-0ubuntu9
There seems to be a huge memory leak in qemu/kvm 0.12.3. After a while,
a virtual machine is using much more memory on the host system, than
actually is in use on the guest system
