Try to change the line: xen_cmdline=3D"dom0_mem=3D2048M cpufreq=3Ddom0-kernel dom0_max_vcpus=3D2 do= m0=3Dpvh console=3Dvga,com1 com1=3D9600,8n1 guest_loglvl=3Dall loglvl=3Dall" To: xen_cmdline=3D"dom0_mem=3D4096M dom0_max_vcpus=3D2 dom0=3Dpvh console=3Dvga= ,com1 com1=3D9600,8n1 guest_loglvl=3Dall loglvl=3Dall" Note that cpufreq=3Ddom0-kernel is likely not functional, and also not a go= od idea. The FreeBSD dom0 kernel has no idea about the real load of the system= , as it doesn't see the load created by VMs. Xen (the hypervisor) is the only one that has the full picture of the system. --=20 You are receiving this mail because: You are the assignee for the bug.=
