------- Comment #1 from veliogluh@xxxxxxxxxx 2008-12-18 13:59 -------
Same situation occurs in my RHEL5.2 x86_64 box with xen-3.0.3-64.el5_2.3 and
kernel-xen-2.6.18-92.1.22.el5. My machine has 16GB of memory and 4 PV machine
which has 4GB of RAM is running on it. So dom0 has 12 GB free memory. However,
when I want to create a hvm domain with virt-install command, I get en error
like "Cannot allocate memory". I have a production Xen system and this problem
had occured twice at there and I solved it with rebooting the machine or
creating another PV domain and after that creating hvm domain again.
But while workin with my test box I could catch the same issue and I want to
dig it without rebooting because I know after reboot it will work. But this is
not a solution.
Here is my xend.log after trying to run hvm domain.

XendError: Error creating domain: (12, 'Cannot allocate memory')
After my investigation I found that in
/usr/lib64/python2.4/site-packages/xen/xend/XendDomainInfo.py in function
self.domid = xc.domain_create(
domid = 0, ssidref = security.get_security_info(self.info,
'ssidref'),
handle = uuid.fromString(self.info['uuid']),
hvm = hvm)
the function xc.domain_create fails. I checked the functions in paramters and
their returns are correct. Here the parameters:
security.get_security_info(self.info, 'ssidref') returns 0
uuid.fromString(self.info['uuid']) returns [93, 227, 91, 115, 79, 87, 65, 4,
32, 5, 79, 128, 90, 188, 56, 118]
hvm is 1
And I write a "log.debug" line both after/before this call and just the before
one worked. So I think I catch the problem line.
I can keep this machine without rebooting so I can try any suggestion.
PS: Sorry for my english.
