Hi Dirk,
I don't have any experience yet, however in the next few days I am
going to test my Ubuntu 10.04 64-bit Dom0 with about 40 64-bit DomUs on my Intel
Xeon Quad Core.
Would the result of this help you?
Thanks
Folks,
thanks a lot for all the feedback. First let me
make clear: I am doing
nothing special. They are standard installs with just
one difference:
the bridged network interface is a bond in some cases (but by
far not
all cases).
The configuration I did is as described:
- pin
cpus
- pin no domU do dom0's cpu
- dedicate a minimum amount of RAM
(mostly 1 GB) to dom0
- dedicate at least 512 MB to each domU, not ballooning
(start amount
and max amount are the same).
So, what I observe from
your answers, is that people having no problems
with Lenny's Xen
implementation are running 64Bit on AMD architectures.
Is there anybody
out there running several intel machines with 32Bit
Lenny Xen and NOT having
any problems with regular crashes?
I will take a look at compiling myself
again (had done so all throught
the 2.x years), but that would mean giving
up. :-)
So let's make a poll out of it:
Anyone here having frequent
crashes with 64Bit Lenny's Xen?
Anyone here NOT having frequent crashes with
32Bit Lenny's Xen?
Each answer please also name the processor
architecture.
Thanks a lot,
Dirk

Like I said, they are all Opteron machines - most dual core, some quad
