Hi  JP P
When you mention de amount of ram, is the max, the default, both? The
discrepancy between the two amounts causes the machine try to expand the
default memory it hungs.

Hi
As you may've seen from my last posts I'm struggling to get the setup on my
subject line to work without flaws.
I've tried compiling the Kernel from Source, I've also tried Fedora 14,
which has a flaky pv_ops Dom0 kernel which DOESN'T work at all, but none of
these seem to work.

I'm a mid-time XEN user, I just love it and want to stay away from KVM  but
the migration path is too rough when you want pv_ops Dom0, and all seem to
be just projects, TODOs and snapshots, nothing really serious IMHO there's
lots of misleading info and there are many gaps on existing howtos, I've
read that SuSE has back-ported some stuff from 2.6.3.x branch into 2.6.18
but I want native and I don't want to be toying around with Debian'ish stuff
in production environments.

I'd like to keep using RH like system because of their robustness and
because I'm used to work with it as a RHCE.
Please, would you help me find a distro which would integrate

RH like XEN 4.0.1pv_ops Dom0 kernel
I want to run telephony stuff on them and tho I kinda got my Openvox A1200P
card to work 50% of the times now with xen 4.0.1 it won't work but I guess
that's because I'm using Kernel 2.6.18.x with XEN 4 which is not
recommended.

Any advise will be deeply appreciated.
Thank you.

Hello,

I get a VM crash while trying to load a database. The "smaller" tables are
loading OK, but When I try a bigger one (#3 000 000 rows) the ASCII dump
file is #766 MB. When I try to load that table the machine crash and I find
always the same message in the "qemu....log' file :

xc_map_foreign_batch: mmap failed: Cannot allocate memory
xc_map_foreign_bulk error 12

I try it with two different flavous of XEn ( 4.0.0 and 4.0.1).

In "/var/log/xen" some messages about VM's crash :

Since Open-OVF appears to be dead in the water, I think the answer is no.

However, I believe XenServer has support (look up Project Kensho). Possibly
this is open source now in XCP.
