Hi,
my Dom0 is running with Fedora Core 6 and overall I would say it works. But I
have a problem with HVM guests: I can start them just after system reboot but
they won't start after I worked some time. "xm create" just gives me the error
message "VmError: (12, 'Cannot allocate memory')".
The error does always appear when my "free" memory (as shown by top) is lower
than the amount required by my HVM guest. What I do not understand is why Xen is
not able to use memory which is used as cache by the Kernel. It is not uncommon
for me to have 2-3 GB memory used as cache but only 20-30 MB free. Furthermore I
expected that even SWAP can be used for my Xen guest which are another 2 GB.
Is there a workaround/bugreport for this behavior? Is there any hope it can be
fixed?
