It shows the same as shows when the guest is able to boot. Guest's zpool is never imported, neither vfs.zfs.vol.recursive is enabled.=20 >2) What does "top" show on the host at that time? Is zfsd spinning the CP= U? Nothing special, among others: 7280 root 18 32 0 12G 32M kqread 10 3:51 100.50% bhyve 6833 root 1 20 0 20M 11M select 26 0:00 0.00% zfsd It is also probably worth mentioning, that I have had from time to time (ve= ry rarely though) problems with importing that pool (booting bhyve guest VM) in the past. It begun in stable/13 somewhere between 13.1 and 13.2 release IIR= C. To fix that I had to enable vfs.zfs.vol.recursive, import zpool from from = the host, perform some writes, for example clear a few snapshots, export zpool = and then the VM booted fine. It wasn't reproducible though. It's worth to menti= on that all that time zfsd(8) was running. Now, after upgrading the bhyve host to stable/14, the problem with booting bhyve guest VM is 100% reproducible and fully dependent on the state of zfsd(8). --=20 You are receiving this mail because: You are on the CC list for the bug.=
