Hi Ed,

I have xen 3.2.0 (from source rpm) built with CentOS 5.2 on
DQ35 box with ACM enabled and the commands in question seem to work.

Do you have xml file beginning with your policy name in /etc/xen/acm-security/policies/?
You must have file called "<your_security_policy_name>-security_policy.xml".
e.g. 'DEFAULT-UL-
security_policy.xml (default policy)

Regards,
Dilshan

Has anyone seen the following errors on CentOS 5.2 with Xen 3.2.1:

# xm list
ACMError: Policy file '/etc/xen/acm-security/policies/-security_policy.xml' not found.
# xm dmesg
Error: (13, 'Permission denied')


I get these every time I do the following:

1. Default install of CentOS 5.2 on Intel DQ35 motherboard system
2. Install mercurial
3. Download xen-3.2.1.tar.gz from xen.org and untar.
4. make world (fails when it can't find linux-2.6.18-xen.hg)
5. hg clone http://xenbits.xensource.com/linux-2.6.18-xen.hg
6. make all (succeeds)
7. make install (succeeds)
8. depmod & mkinitrd
9. edit grub.conf and reboot new Xen kernel

After reboot, I then run "xm list" and "xm dmesg" which used to work but now give the above error.

Evidently it doesn't like my security policy and more -- any thoughts/ideas on why?   Is this a known bug or incompatibility? Is my build/config wrong?

Thanks,
Ed Nadolski
