[ILUG] 64-bit capable box wanted for xen. -- recomendations please..

[macada]

Hi list,

Im not a guru of Xen but Im a member of a LUG in Spain and we have a 
hosting (it's not a hosting at all, just a pice of space). The machine 
is a HP Blade server. Each blade server is a dual AMD 64 bits (AMD 
Opteron(tm) Processor 275) 2.2 Ghz. We have a pice of it with 8GB and 
512 RAM over Xen in 2.6.18-1.2257.fc5xenU (fedora core5)

We are running ubuntu gutsy 64bits and I have to say that some of 
services like apache2 or tc (for qos) dont work well. We have 
experimented crashes like reboots or sometimes web is down (segmentation 
faults). Now the server is running perfectly because I have some scripts 
in cron look after of the services otherwise our server won't work well.

This is my experience. Maybe AMD 64 works well with some redhat kernels 
make for them exclusively for HP.... I dont know.... who knows?

I hope this mail can help u.

Cheers
