https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D212681 --- Comment #53 from Roger Pau Monn=C3=83=C2=A9 <royger@freebsd.org> --- I'm attaching another patch that will allow to selectively disable some PV optimizations, you will have to play with the following tunables, and see if you can find which one(s) causes the VM to go faster: hw.xen.disable_pv_ipi hw.xen.disable_pv_et hw.xen.disable_pv_tc hw.xen.disable_pv_clk hw.xen.disable_pv_disks hw.xen.disable_pv_nics Those tunables should be set in /boot/loader.conf, like: hw.xen.disable_pv_ipi=3D1 Thanks, Roger. --=20 You are receiving this mail because: You are the assignee for the bug.=
