Re: [Xen-users] xm create random error

Hi

Put your dom0-min-mem back to the default - you don't really want it shrinking
to 16M.

done;

Xen is not really good about returning memory to dom0 when you
shutdown a guest (more noticeable with 3.0.3 than 3.1.0). Inbetween Shutting
down a guest after the first boot (which I assume always works) and starting
it again, do a 'xm mem-set 0 512' so xen feels better about taking the
memory.

done also this, but this is the situation:
i've just power on my xen server machine; it starts but no one vm starts:

xentux:~# xm list
Name                                      ID Mem(MiB) VCPUs State   Time(s)
Domain-0                                   0      107     1 r-----     69.9

xentux:~# xm mem-set 0 512

...and if i try to boot a vm:

xentux:~# xm create /etc/xen/xen01etch.cfg 
Using config file "/etc/xen/xen01etch.cfg".
Error: I need 131072 KiB, but dom0_min_mem is 200704 and shrinking to 200704 KiB would leave only -84804 KiB free.

For many days i had no problems (powering on the xen server machine, both xen server and vms boot well), and today it happens again.
Which are the variables that make xen works in this way?

What's wrong?
Thanks!
