[libvirt-users] kqemu

[Zvi Dubitzky]

Hi
we have a  Debian 64 bit system with qemu 0.9.1-10 ( uname -a  = 
2.6.26-2-amd64)  installed . kvm is included and loaded to memory .
Still when we create a VM  we sometimes get the following error message:

libvir: QEMU error : internal error unable to start guest: You do not have 
enough space in '/dev/shm' for the 499 MB of QEMU virtual RAM.
To have more space available provided you have enough RAM and swap, do as 
root:
mount -o remount,size=515m /dev/shm
Or disable the accelerator module with -no-kqemu


after we do the mount we can create the VM . Does that mean that kvm is 
not active because it seems that kqemu
is an old way to do the duties of kvm e.g supply memory to VMs via 
/dev/shm

thanks
