With no 0 domains, I can change the memory dedicated by: 1. Changing the appropriate line in the domain config file 2. Restarting the domain Is it possible to do something similar with domain 0, without rebooting the machine? Something like: 1. Change the memory amount 2. Shutdown domain 0 to only XEN kernel 3. Restart domain 0 Kenneth Power _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
You don''t need to restart domains to change their memory allocation, this includes dom0. Use "xm balloon domid target-mb" to request a domain to "balloon" its memory to the target value. Use "xm maxmem domid max-mb" to subsequently tell Xen to prevent the domain unballooning to more than "max-mb" If you try to reduce a domain to something too small then it''ll have out of memory problems - just think twice when you balloon so you don''t shoot yourself in the foot ;-) Cheers, Mark On Thursday 14 April 2005 19:00, Kenneth Power wrote:> With no 0 domains, I can change the memory dedicated by: > 1.

vm-tools vm script will adjust your dom 0 size down in order to make room for the create. http://www.cs.utexas.edu/users/aliguori/vm-tools/ wm =============== Kenneth Power wrote:>With no 0 domains, I can change the memory dedicated by: > 1.
