https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D237429 --- Comment #8 from Rodney W. Grimes <rgrimes@FreeBSD.org> --- Something that jumps out is: warning: total configured swap (58982400 pages) exceeds maximum recommended amount (16155552 pages). You have ~60G of swap space configured, the system only has 16G of memory, do you actually expect to over commit near 4x on memory? To go with this the 3 vm's you show are 4G in memory size, so they would need 12 of the 16G for guests, leaving your host running ZFS with only 4G of memory. Have you tuned the arc cache to be < than say about 2G as with just these 3 VM's your gong to start having memory pressure. I see 16 tap devices configured manually, this is normally handled by vm-bhyve, but leads me to the question how many VM's are you trying to run at once and what is the total memory footprint? --=20 You are receiving this mail because: You are the assignee for the bug.
