Re: [Xen-users] Error creating domain: (12, 'Cannot allocate memory')
How do I set that up? I have tried setting the dom0_mem argument in
grub, I have tried setting the mem argument in grub, I have tried to
use balloon, etc, all to no avail.
When I run xm info, I see that there is 435 MB free. Why is this not
being used?
Thanks in advance.

Good leaders being scarce, following yourself is allowed.

I have Centos 4.1 running on Xen (Dom0), and it works fine.
However,
when I try to start a new domain via xm create, I get the
following
error:
Error: Error creating domain: (12, 'Cannot allocate memory')
I have 512 MB on the machine.
Here are some copies of output:
[root@persephone rc3.d]# xm list
Name Id Mem(MB) CPU State Time(s) Console
Domain-0 0 57 0 r---- 88.2
[root@persephone rc3.d]# xm info
system : Linux
host : persephone
release : 2.6.11.10-xen0
version : #1 Sun May 22 11:38:50 BST 2005
machine : i686
cores : 1
hyperthreads_per_core : 1
cpu_mhz : 400
memory : 511
free_memory : 435
[root@persephone rc3.d]# cat /etc/xen/xen.conf
kernel = "/boot/vmlinuz-2.6-xenU"
memory = 128
name = "Test"
disk = ['phy:hda5,hda5,w']
root = "/dev/hda5 ro"
After running the command, I have some seemingly zombie domains:
[root@persephone rc3.d]# xm create /etc/xen/xen.conf -c
Using config file "/etc/xen/xen.conf".
Error: Error creating domain: (12, 'Cannot allocate memory')
[root@persephone rc3.d]# xm list
Name Id Mem(MB) CPU State Time(s) Console
Domain-0 0 57 0 r---- 90.4
Domain-6 6 128 0 --p-- 0.0
I have to kill them using xm destroy Domain-X. Note that I
do not
specify the name of Domain-X; instead, it is supposed to be
called
Test.
I have tried using balloon to adjust memory on Dom-0, and
while that
works (xm list shows the new amount being used), it does not
allow me
to create any new domains.
Thanks in advance for the help!
