Add emulators/py-nova 14.0.2, Openstack Compute Service

Please note that this is a development version of nova. Many features are not available. Currently nova works on FreeBSD 11 and supports QEMU and Xen. Common issues: - Security groups are not implemented - ARP spoofing, DHCP isolation protection are not implemented - Nova services work from the root user - No IPv6 support QEMU issues: - Need to enable serialconsole (TCP) - Need to disable online CPU tracking - Cannot mount cinder volumes Xen issues: - Live snapshots don't work - No support for cinder volume hot-plugging - XENBUS delay (5 min) when using qemu driver and COW images - Some Linux images cannot be booted For further FreeBSD specific notes please refer to port's pkg-message. PR: 215151 Submitted by: Alexander Nusov (alexander.nusov@nfvexpress.com)

+Please note that this is a development version of nova.
+Many features are not available.
+
+Currently nova works on FreeBSD 11 and supports QEMU and Xen.
+
+Common issues:
+- Security groups are not implemented
+- ARP spoofing, DHCP isolation protection are not implemented
+- Nova services work from the root user
+- No IPv6 support
+
+QEMU issues:
+- Need to enable serialconsole (TCP)
+- Need to disable online CPU tracking
+- Cannot mount cinder volumes
+
+Xen issues:
+- Live snapshots doesn't work
+- No support for cinder volume hot-plugging
+- XENBUS delay (5 min) when using qemu driver and COW images
+- Some linux images cannot be booted
+
+Nova requires procfs to be mounted.
+Please add this line to /etc/fstab:
+proc                /proc           procfs  rw      0       0
+
+Also devel/libvirt port should be installed with enabled QEMU
+backend or qemu tools installed separately.
+
+Directory to keep VM data should be created manually
+# su -m nova -c "mkdir /var/lib/nova/instances"
+
+For proper networking enable PF
+# sysrc pf_enable="YES"
+# sysrc pflog_enable="YES"
