Your disk name has changed. I don't known enough about FreeBSD but if you've chosen a virtio disk for your VM its device name should be something like "vtbd..."

I use qcow2 , I install centos in proxmox , and when I use df -h command I see

 mpfs                 750M     0  750M   0% /dev/shm
/dev/sda1             477M   57M  395M  13% /boot

And what is the link between qcow2, CentOS and your migrated FreeBSD machine?

If you type ufs:ad0s1a to mount root does it work?

I told you I don't know about FreeBSD. You should need to fix the root device first (in /etc/fstab and wherever else is specified for booting), then the /dev entries, maybe.

I mount all partition and when I run this command

/usr/bin/vi  /etc/fstab

I see this and I can not change fstab

Looks like you have /usr on a separate partition? Although then you wouldn't be able to run vi...
Can you find the getty executable where the other screenshot claims it's missing?

To avod problems with changing device names in the future: hook in a freebsd live-cd, boot from it, assign labels[1], fixup your /etc/fstab and /boot/loader.config's vfs.root.mountfrom to use the label.

I see this and I can not change fstab

On boot, the root volume is read-only. To fix this, type

mount -u /

to update the mount from ro to rw. You can then edit the fstab file.

Also, if possible you should label your file systems with

tunefs -L

and then change the direct device names to the label names in fstab so that the underlying disk type does not matter anymore.
