This thread suggests that mmconfig might be the issue, in which case
does adding "mmcfg=0" to your hypervisor command line help?

I'd recommend continuing to pursue this upstream, there are far more
experts on the low level aspect of things there.

Hi,

First of all, thanks for your help.
I have made some test with this results
debian testing with xen 4.4 can run if we add mmcfg=0 as boot options
to kernel boot parameters !!! Remember that with xen kernel <=4.0
works perfect without to add mmcfg=0

I have tried to install citrix xenserver 5.6 and works perfect
(remember that this is xen 3 branch)
Also we have tried to install xenserver 6.2 but during boot install using:
menu.c32 and add boot parameter mmcfg=0
and after to install  boot we have added mmcfg=0 in extlinux and
executed extlinux -i /boot to update bootloader


With this seems to work, and it could be a possible workaround?

My questions are:
- mmcfg: I'm not sure where is used and what happen if we use xen
without mmcfg. Why with xen <=4.0 is not needed anb for xen >4.0 is a
requirements for this hardware. Will be solved?
- Can I use for production environment this configuration?


Thanks
