Re: Xen-hypervisor 3.2 on HP Proliant DL380 G6

[Emanuel dos Reis Rodrigues <emanueldosreis@gmail.com>]

Hi all,


Only to register,   after my tests ...


HP DL380 G6 is not compatible with xen-3.2 on Debian Lenny kernel 2.6.26.


The HVM hosts hangs on boot.


My tests with Debian Lenny 2.6.26-2 xen kernel   and  Xen-3.4.3 works 
fine and without problems.
