I'll be straight . You already got a nice feed from jkeil. Some time ago i did
testing
suggested by Jurgen and there was some rush from my side :-
installs SNV85 DomU (with kmdb involvment) at Xen 3.2 Linux (CentOS5.1,Ubuntu
7.10) Dom0 (64-bit). I performed sequentially two installs with hard initial
runtimes in about 1.5 hr.
Linux Dom0s just multibooted on the same host C2D8400, ASUS P5K Premium /WIFI,
4GB RAM , 2x250 GB Seagate Barracuda Drives (7200 rpm, 16 MB controller cashe).
South Bridge ICH9R obviously set in AHCI mode.
Install at Xen 3.2 Ubuntu 7.10 Dom0 ran faster (no issues with NCQ support from
Ubuntu side).
I hardly remind CR for CentOS 5.1, reagarding SATA 2 support (NCQ in
particular) .
Even this issue on CentOS 5.1 noticably slows down Solaris DomU the very first
runtime ( jkeil wrote you about it in details).
My suggestion - stay away from AMD, regardless it's harware is inexpensive.
C2D6750, ASUS P5K(E) Deluxe, 4GB-8GB RAM plus SATA Drive as faster as better
would run Solaris PVMs fast enough. WD Raptors are prefferable drives in my
opinion,
Seagate Barracuda much slower (and cheaper) .
