Hi
I have serveral questions concering xen.
I installed the Novell xen-3.1.0-1.i686.rpm
and kernel-xen-2.6.18-3.1.0.i686.rpm
on my openSuse 10.2 System and tried to start. What I got was a
"Mismatch between Xen and Dom0 Kernel" panic (See pict).
What did I do wrong or do the rpm files not really work/match?
Hence I installed the sources and compiled them all (?). After also
compiling the hmvloader with the dev86 package and installing it all, I
was able to start Dom0 (seem to work fine so far) and to start DomU in
order to install a native WinXP from the CD-Rom. The Dom0 Window pops
up for some seconds and disappears again, not long enough to read
anything (according to the log due to poweroff; who did poweroff?).
I something must still be wrong, but what? Appreciate any help/idea!
And last but not least. One of the reasons why am doing all this,
besides of getting to know xen, is that a have a windows slideshow
program running on VMWare with a very poor video performance
(flickering picts instead of alphablending, messy timing). My hope was,
that with xen and Pacifica I could get near native performance.
Does anyone have experience with xen/Pacifica and video perfomance?
Does it get near to native WindowsXP?
Cheer for your ideas
