[Xen-users] GPL Xen vs XenSource? Supported memory amounts on 64bit?
What is the maximum physical memory supported by the GPL Xen version? I''m only concerned with 64bit machines (64bit Dom0). Are there simply no programmed limits on the GPL Xen included in distros like RHEL? I know that for XenSource v4 by Citrix, the limits are: Express Edition 4GB RAM physical, 2 CPU sockets, 4GB RAM per VM, max of 4 active VMs Standard Edition 128GB physical RAM, unlimited CPU sockets, 32GB RAM per VM, unlimited active VMs Enterprise Edition 128GB physical RAM, unlimited CPU sockets, 32GB RAM per VM, unlimited active VMs, _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

I know that xen 32 bit has a hardcoded limit of 12 GB also using pae. About xen 64 bit it could have another hardcoded limit: the 64 bit arch should map 16 exabyte.... However I''m using xen 3.2 64 bit with 26GB of ram. marco 2008/5/14 Thomas Harold <tgh@tgharold.com>:> What is the maximum physical memory supported by the GPL Xen version?

We were using Xen on a 4GB box before and the new boxes will be either 8GB or 16GB 64bit units (running 64bit Dom0). _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
