[Xen-users] xm console domU

["Ferreira, N.L." <N.L.Ferreira@xxxxx>]

Dear *

Just starting to play a bit with this new world of virtualization.
Installed a guest domain (Scientific Linux), either using xen-strap or virt-install.
Till now, they seem to work just fine. Nevertheless, I have one question.

After starting a guest domain with "xm create domainID" (see xen config file below), I connect to the console of domU with "xm console domainID".
When working on linux, I usually open several console windows to perform different tasks. But if I try to connect to a 2nd console on the same domU,
both consoles freeze. I noticed that the commands issued in one console do appear in the other console. A "who" command inside of the domU shows that only one device (port? I do know the syntax) is open (xvc0).

How can I connect to  a console domU more than once,without problems? Probably is some variable on the xen config file, but after reading the manual I still could not figure it out.

Cheers,
Nuno
