Does Ubuntu lucid support more than 32 GB of ram? I have a XEN server running a PV guest. I upgraded from 32 to 64 GB RAM. The domain0 (host) sees all the RAM and starts the domainU (guest) with all the RAM. But inside the guest OS I can only see 32 of 64 GB RAM. I think this is a limitation of ubuntu 10.04 because the xentop command give me the guest with all the RAM. Domain0 (host) specifications : - Ubuntu 12.04.2 LTS - 3.5.0-34-generic kernel - 64 bit - all RAM is addressed DomainU (guest) specifications : - Ubuntu 10.04.4 LTS - 2.6.32-40-server kernel - 64 bit - ParaVirtualized - it sees only 32GB of 64 GB RAM. There was no problem while upgrading from 16 to 32 GB. This is very similar to this old topic: http://old-list-archives.xenproject.org/xen-users/2011-06/msg00393.html But I guess I already have the newer kernel... Thanks to everyone. -- View this message in context: http://xen.1045712.n5.nabble.com/Can-be-installed-more-than-32-GB-RAM-on-Ubuntu-10-04-64-bit-XEN-VM-tp5728143.html Sent from the Xen - User mailing list archive at Nabble.com. _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxx http://lists.xen.org/xen-users
