2018-02-01 Upgrade to OVMS 3.3.4 - Attempt #2
Overview
Since I struck a problem with a multipath device being created on an unused partition (see 09 Upgrade to OVMS 3.4.4), I was not able to create the /OVS file system. I had to re-install OVMS again.

Procedure
Install OVMS 3.4.4
Following the procedure in 2.1.2 Installing Oracle VM Server From a DVD-ROM, I generated the following partial Kickstart installation file (found in /root/anaconda-ks.cfg):
install cdrom lang en_US.UTF-8 keyboard us network --onboot yes --device eth0 --bootproto static --ip 192.168.1.100 --netmask 255.255.255.0 --noipv6 --nameserver 192.168.1.1,192.168.1.252 --hostname victoria ovsagent --iscrypted **********************************************************************************************************
ovsmgmntif eth0 rootpw --iscrypted **********************************************************************************************************
firewall --service=ssh authconfig --enableshadow --passalgo=sha512 selinux --disabled timezone --utc Australia/Sydney bootloader --location=mbr --driveorder=sda --append="rhgb quiet"
# The following is the partition information you requested # Note that any partitions you deleted are not expressed
# here so unless you clear all partitions first, this is
# not guaranteed to work
#clearpart --all --drives=sda
#part /boot --fstype=ext4 --size=500
#part /OVS --fstype=ext4 --grow --size=894432
#part / --fstype=ext4 --grow --maxsize=51200 --size=4096
#part swap --grow --maxsize=7736 --size=1024
This was generated (in part) through choosing Create custom layout under Disk Partition Layout.
This enabled me to create the /OVS file system on its own disk partition.
Create Bridges
Following the procedure in 07 Set Up XEN Network, I ran the following commands to create the four (4) bridges that support the networks used by the VM images:
cd /etc/sysconfig/network-scripts
for bridge in 0 1 2 3
do
nw=$(((bridge + 1)))
bridgename="xenbr${bridge}"
# ==== Create bridge
cat <<DONE >ifcfg-${bridgename}
# -----------------------------------------------------------------------------
# Bridge ${bridgename}
# Generated $(date +"%F %T")
# -----------------------------------------------------------------------------
# Device identification
DEVICE="${bridgename}"
UUID="$(uuidgen)"
# Device options

TYPE="Bridge"
ONBOOT="yes"

NM_CONTROLLED="no"

DNS2="192.168.1.1"
PEERDNS="yes"

DONE
done
Attach XENBR0 Bridge to ETH0
Attached the xenbr0 bridge to the eth0 NIC as follows:
cd /etc/sysconfig/network-scripts
cat >>ifcfg-eth0 <<DONE
# Bridge
BRIDGE="xenbr0"
DONE
Create Sub-Interfaces on ETH1 and Attach Other Bridges
Create three (3) sub-interfaces on the eth1 NIC and attach the last three (3) bridges to each of them:
cd /etc/sysconfig/network-scripts
for subif in 1 2 3
do
bridge=${subif}
ifname="eth1:${subif}"
bridgename="xenbr${bridge}"
# ==== Create subinterface
cat <<DONE >ifcfg-${ifname}
# -----------------------------------------------------------------------------
# Sub-interface #${subif} on eth1 to support bridge ${bridgename}
# Generated $(date +"%F %T")
# -----------------------------------------------------------------------------
# Device identification
DEVICE="${ifname}"
UUID="$(uuidgen)"
$(grep HWADDR ifcfg-eth1)
# Device options
ONPARENT="yes"
TYPE="Ethernet"
MTU="9000"
ONBOOT="yes"
NM_CONTROLLED="no"
# Bridge
BRIDGE="${bridgename}"
DONE
done
Restore VM Images
The VMs that were saved from VICTORIA, were restored using the following commands:
