Hello, I got Centos 5 installed on my server (Linux srv1.local 2.6.18-238.12.1.el5xen #1 SMP Tue May 31 14:02:29 EDT 2011 x86_64 x86_64 x86_64 GNU/Linux). Then I put Debian x64 6 in DomU with 2GB of RAM. It works perfectly. Recently I increase RAM for this VM to 4GB and it starts to hang randomly. I think it hangs when try to use more than 2 GB (may be more) of RAM. So I created new VM with 4GB of RAM. Boot with debian 6 netinst iso and it hangs during install. I decrease memory to 2GB and installed it without a problem. Windows Server works perfectly with 5GB of RAM on this server. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
