[Pkg-xen-devel] Bug#760563: Bug#760563: xen-hypervisor-4.4-amd64: Xen >=4.1 not booting on IBM HS20

[Trenta sis]

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
