https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D261059 Roger Pau Monn=C3=A9 <royger@freebsd.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |royger@freebsd.org --- Comment #3 from Roger Pau Monn=C3=A9 <royger@freebsd.org> --- Using only 2GB of memory for dom0 together with ZFS is likely too less, you should use at least 4GB of memory for dom0 when using ZFS. 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.=
