Hello everybody, First I need to mention this is my first contact with Xen and virtual machines at all. I compiled the xen linux kernel, installed xen, tools, etc. and just booted for the first time with the xen-linux kernel. Well, it works but it''s not really possible to work on this machine. The performance is terrible. For example, it takes up to 1-2 minutes until I can switch between windows or to open the terminal. It took like incredibly long time after booting to show the initial Ubuntu screen, probably 5 minutes or longer. I can even hardly move the mouse and as soon as I try to open a program (terminal or firefox) everything freezes. I got Xen 3.4 with kernel 2.6.18. I would be happy if you could point me to some probable solutions or the issue I might be having. I got no no idea what the problem could be. Thank you all in advance!

Hi, Try to disable the TLS libraries. mv /lib/tls /lib/tls.disabled Regards, Nikola On Thu, Jun 25, 2009 at 1:31 PM, <elli_dberg@web.de> wrote:> Hello everybody, > > First I need to mention this is my first contact with Xen and virtual machines at all. > > I compiled the xen linux kernel, installed xen, tools, etc. and just booted for the first time with the xen-linux kernel.

Hi Nikola, thank you for your quick response. I tried to disable them but there was no /lib/tls to be moved. Do you think this might be the problem - that i don''t have tls?

Hi all, I''d like happily to announce that I could fix the problem. I don''t know how exactly I did this, but it seems it was a memory and X problem. A friend of mine told me to check the output of vmstat and what turned out is that the machine was swapping too much. I set the dom0 memory to 512Mb and after several X reconfigurations it works now pretty well. Hope this helps other too.
