Hi,
Can UML use more than 4GB of the hosts memory in total (like MySQL
can't) due to the 32bit limitation? Or, with High Mem, will it support
upto 64GB?
Thanks,

Does anyone know how UML behaves with multi-core systems? Does the
process glue to one core for as long as it runs for, or use all cores
whenever it wants?

Did you check if you could ping the host machine. If you can, but
can't ping the world, check if your IP Masquerading is on. E.g.
iptables -t nat -I POSTROUTING -o eth0 -j MASQUERADE

Hello,
Apologies if my question is too simple for you :-)
I have a server (accessible only via SSH really) and I want to run a
UML instance so I can use some kind of VNC to connect to it. Is this
possible? I have experimented with X11 forwarding, but without luck.
Is this the way forward?
Thanks
I'll probably be proved wrong here, but I use ubda as ubd0 (/dev/ubda)
and ubdb as swap (/dev/ubdb) (only seems to work as swap) then ubdc
etc are more filesystems.
Sorry If this doesn't help you, I'm no UML know-it-all.

Hello,
This may sound like a daft question, because, it probably is :-)
Is there a way to boot a Windows Image with User Mode Linux. Only
thinking of this because "Virtuozzo" can do it (don't worry, UML is
still far superior =D).
Any input it greatly appreciated.

Hi Gordon,
While this answer may not be what you're looking for, here goes:
I had that issue a few days ago, so I simply went for the 2.6.20
kernel anyway, and patched that with the latest one. For me, it was a
safer bet. I did, however, use the 2.6.23 kernel for UML Guests.

Hi,
2) You can get some good root filesystems from:
http://uml.nagafix.co.uk/
You may want to try "damn small linux", I've tried it on my personal
PC, but I haven't run it within UML as of yet.
3) How short?

Hi,
I've managed to setup "tap0" and get it configured with UML, which is
all great. UML has an external IP address, which is fine for inbound
connections, but, is there any way you can change the source IP of the
outgoing packets, for example:
Host Machine: 1.1.1.1
UML: 1.1.1.2
