instead you need to export and mount each child filesystem separately. this is compatible on both the host and guest side with virtio-9p in Linux and other operating systems, but not with the newer version which i can't remember the name of (VirtFS?). --PU+L0fM/35rm4EcR Content-Type: application/pgp-signature;

I have have alread= y tried it with a linux (debian) guest and it works fine too.
I= 9;m looking for p9fs support on windows guests but for what I digged, there= is no 9p support yet but I also found that microsoft uses it on linux subs= ystem...

If you know a program that do 9p on windows, please s= hare.

Thanks,

this is what p9fs(4) is for.

> promising, am not sure this can be accessed from the host.

p9fs exports an existing directory tree from the host (similar to the
NFS server), so the host can always access the files by definition.

to export the filesystem, add a virtio-9p device to bhyve:
=C2=A0 =C2=A0 =C2=A0 =C2=A0 bhyve [...] -s 5:0,virtio-9p,myshare=3D/some/pa= th,rw
'myshare' should be replaced with a descriptive name for the share,=
and change 'rw' to 'ro' to make it read-only.

in the guest, mount the filesystem as normal in /etc/fstab using the
same share name:
=C2=A0 =C2=A0 =C2=A0 =C2=A0 myshare=C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0/mysha= re=C2=A0 =C2=A0 =C2=A0 =C2=A0 p9fs rw 0 0

note that unlike NFS, this doesn't work automatically for descendent mountpoints on the host (e.g., ZFS filesystem hierarchies); instead
you need to export and mount each child filesystem separately.

this is compatible on both the host and guest side with virtio-9p in
Linux and other operating systems, but not with the newer version
which i can't remember the name of (VirtFS?).

Since moving to 15.0-ALPHA1, I have a more formal test regime of testing th= e VM with different memory allocations and with and without host reboots. On 15.0-ALPHA1, the VM's behave in three ways from what I can tell: 1. Fail quickly with the Assert 2. Take several minutes or seconds to Assert 3. Hang for around 12 hours with 100% load for the bhyve process at which p= oint I terminated it. I have tried a different storage model but I welcome your advice on what ot= her parameters to change to help isolate this.

}; This is why a limit of 16 was hardcoded. The changes to amd64 to enable la= rger vCPU counts replaced these static arrays with dynamic arrays allocated at VM creation. arm64 support was added after these changes had been merged into amd64 and arm64 has always used the new dynamic arrays approach. On both amd64 and arm64 (and probably RISC-V, I haven't looked), the default limit on the number of vCPUs is the number of physical CPUs on the host.=20 However, that limit can be changed via the hw.vmm.maxcpu loader tunable. What behavior are you seeing with arm64 bhyve in your testing that looks li= ke a 16 vCPU limit? --=20 You are receiving this mail because: You are the assignee for the bug.= From nobody Sun Sep 14 03:46:12 2025 X-Original-To: virtualization@mlmmj.nyi.freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2610:1c1:1:606c::19:1]) by mlmmj.nyi.freebsd.org (Postfix) with ESMTP id 4cPYx00C4nz67FMv for ;
