The dynamic disk feature of Windows Server is quite efficient when it comes to work into a Sun xVM environment. The 30 GB disk "Disk 0" is handled by the OpenSolaris Dom-0 as a ZFS block volume:

pascal@teroknor:~# zfs list xvmpool/bajor.zvol
NAME                       USED  AVAIL  REFER  MOUNTPOINT
xvmpool/bajor.zvol        30.1G   327G  30.1G  -

To grow this "disk", just set the volsize property:

pascal@teroknor:~# zfs set volsize=60G xvmpool/bajor.zvol

Result:

pascal@teroknor:~# zfs list xvmpool/bajor.zvol
NAME                       USED  AVAIL  REFER  MOUNTPOINT
xvmpool/bajor.zvol        60.1G   327G  30.1G  -

After a Windows Dom-U reboot, the disk is "bigger":

The additional space appears as unallocated:

Sure enough, you can expand the volume (right-click, "Expand...").

End result:
