It would be nice to have some examples of the suitable XML for running
a parallels container shown here too. That can be done as a later follow
up patch though. No need to change this patch though - I'm happy to see
it as a later addon patch.

Hmm, perhaps I'm misunderstanding, but isn't Parallels a container
based technology like OpenVZ, rather than full machine virtualization ?
For containers we use 'exe' as the os type rather than 'hvm', and I'd
expect the arch + bit count to match the host OS.

How do connections from parallels work from an end user POV ?
Is there is a single parallels service for the whole machine
which all users connect to, or does each user have their own
private service they work with.
If the former, I think it'd be preferable for the URI to be
either simple
parallels:///
Or
parallels:///system
to have a bit closer alignment with the naming we use with
LXC / QEMU / OpenBVZ.
If the latter, then I'd suggest parallels:///session to
indicate its tied to a per-user account/session.
+static int
+parallelsGetVersion(virConnectPtr conn ATTRIBUTE_UNUSED, unsigned long *hvVer)

For this I reckon you basically want to return the version of the parallels
software.
+int
+parallelsRegister(void)
+{
+ char *prlctl_path;
+
+ prlctl_path = virFindFileInPath(PRLCTL);
+ if (!prlctl_path) {
+ virReportError(VIR_ERR_INTERNAL_ERROR, "%s",
+ _("Can't find prlctl command in the PATH env"));
+ return VIR_DRV_OPEN_ERROR;
You can just return '0' here, and rather than reporting an error,
you want to just log a VIR_DEBUG statement I reckon, since you
don't want to cause initialization of libvirt as a whole to fail
just because parallels isn't installed.
+ }
+
+ VIR_FREE(prlctl_path);
+
+ if (virRegisterDriver(¶llelsDriver) < 0)
+ return -1;
+
+ return 0;
+}
If you can either answer my questions or address them, I'd ACK this now.
