Is there a way to discovery how much free memory I still have to use in a new domain? Another question is about cpu usage. I guess that xen scheduler allocate a fixed time slice for all virtual machines and does not make any idea if the virtual machine is using or not using all this time, right? How I can identify if CPU is the bottleneck?

Someone that knows how XEN works may help us here. -- Flávio Bruno Leitner <fbl@conectiva.com.br> [ E74B 0BD0 5E05 C385 239E 531C BC17 D670 7FF0 A9E0 ] ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.

''xm list -l'' includes cpu_time, up_time and start_time for each domain.

Hi there! I am just writing some documents on vif setup (network and vif setup scripts) and I noticed that xend does not supply ip parameter (and therefore vif-route script is so dumb). You might already know about the issue. What are the chances of having this added? (Unfortunatelly I do not know Python - otherwise I would try to do it myslef).

It''s another sub-option, like specifying the MAC address. -- Keir> Cheers > Gregor > -- > Quidquid latine dictum sit, altum viditur --- Anon > > > ------------------------------------------------------- > The SF.Net email is sponsored by: Beat the post-holiday blues > Get a FREE limited edition SourceForge.net t-shirt from ThinkGeek. > It''s fun and FREE -- well, almost....http://www.thinkgeek.com/sfshirt > _______________________________________________ > Xen-devel mailing list > Xen-devel@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/xen-devel >------------------------------------------------------- The SF.Net email is sponsored by: Beat the post-holiday blues Get a FREE limited edition SourceForge.net t-shirt from ThinkGeek.

Each vif would need a separate IP for routing to work. vif-route doesn''t set up the route either. So what would be a good scheme? 169.254.X.Y for vifX.Y? A domain may get different vifs at different times, and a different IP for the vif would interfere with using NFS root from dom0 (nfs_server would be always different). What about a vif_ip or similar option in the domain configuration file? -- /Varga Péter/ ------------------------------------------------------- The SF.Net email is sponsored by: Beat the post-holiday blues Get a FREE limited edition SourceForge.net t-shirt from ThinkGeek.
