Yes to both. I am running a pair of these on VMWare hosts (using the 
15.1 "unified package" image).

There are a couple of things I have come across. First the VM's have a 
constantly crashing and core dumping process, l2cpd.

As an example of what happens:

Jul 27 15:33:56  vrr1 l2cpd[34141]: stp_enable_modules : Failed to get 
stp base mac address.                       All modules will remain 
disabled.

That happens every minute.

The second issue is you cannot configure the em0 interface. I only need 
a single interface on these VM's but I have had to add two interfaces. 
The first interface I have just left disconnected so that the real 
interface gets bumped to em1 which can be configured.

If you try to configure em0 this happens:

[edit]
me at vrr1# show interfaces em0

[edit]
me at vrr1# set interfaces em0 description test

[edit]
me at vrr1# commit
[edit interfaces]
   'em0'
     Interface em0 is not user configurable
error: configuration check-out failed

[edit]
me at vrr1#

I have not tried any of the earlier images and I have not tried to run 
this with other virtualisation so YMMV.

Apart from the above issues everything else is working perfect for my 
situation.
