vnc password / port - HVM win2k3 guest icmp latency

vnc password / port - HVM win2k3 guest icmp latency

[Sébastien RICCIO]

Hi,

I posted on the same topic this morning, but I don't know if my
msg got through.

I am looking for a patch to enable authentication for HVM vnc
servers. Is one available ? (i read something about it but can't
find the file...)

Also two other questions:

Is it possible to specify which vnc port each HVM listen to ?

Finally, my last question :) :

I played with win2k3 guests, and when pinging them
from domain0 I get 5-20ms reply times.
Is it normal ? Are there some tweaks for this ?

Thanks a lot for reading me.

Best regards,

It was merged into xen-unstable.hg shortly after 3.0.3 was released.
The patches are also in the mailing list archives.

Not directly - you instead specify the display number, eg

    vncdisplay=5

...makes it listen on 5905.

Dan.

Hi again,

I just reinstalled everything using the xen-unstable.hg.

Xend just doesn't start anymore. Watching the logs it was looking
for python-pam module. I found the source for it and installed it.

Tried to start xend again, but no success. It just says it can't find
Domain 0 and dies.

Is there something special to do when "upgrading" from 3.0.3 to
the latest unstable ?

I think it might be something about  Error: (13, 'Permission denied'), but
denied on what ? :)

Reverted temporarily to 3.0.3 and everything run smooth again.

Thank you for your help,

Sébastien

You need to have your userspace tools (libxenctrl and libxenguest) match the
version of Xen that you're using.
