Re: [Xen-users] Xen on Debian Lenny quite unstable

just to confirm: using around 10 instances with lenny
64bits both on dom0 and domU and no issues so far.
might something with bonding? I've read (I'm far from an expert) some
issues with bonding and xen that might cause your arbitrary crashes?
There are issues with bonding and bridging used together, but AFAIK far
from causing crashes. By the way, the machines not using bonding crash
similarly.

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

I have quite a few machines running both intel and amd cpus with the
debian packages for 3.2 from 4gb ram up to 64gb and no problems. I
also pin cpus and don't share dom0's cpu with any domU's. My guess is
hes doing something strange to trigger it? I know there are some known
bugs in that version but i have upwards of 10 machines running it with
very high uptimes.

I don't know what it is that makes you say this, but Lenny's stock Xen
packages (64 bit) have been very reliable for me.
I have more than 10 machines running that setup. Some have only 8G of
ram; I
have a few 32GB machines and one 64GB machine. They run anything from
10 to
close to 40 domUs.
And they are rock solid.
Like I said, they are all Opteron machines - most dual core, some quad
core.
Perhaps the problems you are seeing are caused by Intel-specific
codepaths?
Thanks,
Ward.
