I have been struggling with Xen for weeks. Everytime I would try to launch a guest install, it would fail. From a root prompt, I would execute:
xenguest-install.py -n xm-guest-1 -f /dev/vg0/xm-guest-1
-l ftp://192.168.0.102 -r 256 -p -x text
Everytime I would get the same failure:
Starting Install...
libvir: Xen Daemon error : POST operation failed: No such domain xm-guest-1
In the /etc/log/xend-debug.log I would see:
VmError: I need 262144 KiB, but dom0_min_mem is 262144
and shrinking to 262144 KiB would leave only 243948 KiB free.
...Or some such nonsense.
Much to my dismay, if I reduce the memory footprint of Dom0 to 128:
xm mem-set 0 200
...It works!
Now if I could only get the network to function!

In experimenting with this, I have found that xm mem-set 0 248 does not work, but xm mem-set 0 232 does. There seems to be something special that happens between those two numbers. Using 232 instead of 200 gives the master domain an extra 32meg of memory.
