I''ve been having intermittent issues with Xen not loading up. I read on here that disabling milestone (svc:/milestone/xvm:default) would fix the problem which partially worked. If I disable milestone and reboot it fails but enabling it again and doing a 2nd reboot causes xen to load up correctly. At which point I noticed that during the sessions in which xen wasn''t loading I saw my full 12GB memory but when xen loaded I saw varying amount of memory (1GB / 2GB etc). I only have one xen dom running at the moment consuming 2GB. Also when the memory showing (via top) was 1GB the system was acting very sluggish. I found an article mention ZFS ARC but the article was marked deleted last month so wasn''t sure if that was the cause (also if that was the cause why would it show the available memory only 1/2GB instead of 12 but 10 or so consumed by some ZFS related process?) FYI I''ve set the arc-max to 4GB -- This message posted from opensolaris.org
Turns out the svc milestone itself was causing the problem, it by default sets dom0 to 2GB or 1/2 the memory size (which went from 2 to 1 on the 2nd attempt somehow). I set it manually to 4gb which is holding. Wouldn''t it be better to not specify dom0_mem_size and let it consume as much as needed and releasing as domU''s come up? -- This message posted from opensolaris.org
