If the guest utilities are installed, use Xencenter to shutdown. If not, or, if you just prefer command line - you'll find that shutdown -p will actually take the vm down "correctly". Also - the slow screen display inside xencenter console has also always been an issue. I've never seen it work well. Not sure if this is a freebsd or xen based (with freebsd, as other guest os's seem to get it right) issue. Would love to see it fixed, but... we only use the xencenter console for freebsd long enough to assign an IP and open up ssh ;) Jay West, President EZwind.net 11 The Pines Court, Suite B Chesterfield, MO 63141 P: 314-781-1800 F: 314-558-9284 E: jwest@ezwind.net W: www.ezwind.net -----Original Message----- From: owner-freebsd-xen@freebsd.org [mailto:owner-freebsd-xen@freebsd.org] On Behalf Of Big Lebowski Sent: Saturday, March 29, 2014 9:17 AM To: freebsd-xen@freebsd.org Subject: Re: Terrible performance of XenServer 6.2 and FreeBSD 10.0-RELEASE guest In addition to that, I've also noticed that even with xe guest utilitiest installed and started, neither halt nor shutdown -h now are working (they seem to stop the guest OS, but the vm stays up for the hypervisor and needs to be forced to shutdown/restart) and that the XenCenter console is not refreshing properly (it requires some additional movement, like cursor keys being used to refresh the screen).
