• If you upgraded from XenServer 5.6 GA or 5.6 FP1 to XenServer 6.0.2, change any VMs
that have the OS type CentOS 5.5 (32-bit), CentOS 5.6 (32-bit), CentOS 5.7 (32-bit), Oracle
Enterprise Linux 5.5 (32-bit), Oracle Enterprise Linux 5.6 (32-bit), Oracle Enterprise Linux 5.7
(32-bit), Red Hat Enterprise Linux 5.5 (32-bit), Red Hat Enterprise Linux 5.6 (32-bit) , or Red
Hat Enterprise Linux 5.7 (32-bit) to Other Linux (32-bit). Change any VMs that have the 64-bit
versions of these same OS types to Other Linux (64-bit).
9.16.3. Installing CloudPlatform XenServer Support Package (CSP)
Ensure that you install CloudPlatform XenServer Support Package (CSP) to enable security groups,
elastic load balancing, and elastic IP on XenServer.
If your hosts on versions prior to 6.2 operated on bridge mode with CSP packages installed, after
upgrade, run only the following to restore the desired Security Groups configuration:
1. If the XenServer host is part of a zone that uses basic networking, disable Open vSwitch (OVS):
# xe-switch-network-backend bridge
2. Restart the host machine when prompted.
3. If you are using XenServer 6.1 or higher, perform the following:
a. Run the following commands:
echo 1 > /proc/sys/net/bridge/bridge-nf-call-iptables
echo 1 > /proc/sys/net/bridge/bridge-nf-call-arptables
b. To persist the above changes across reboots, set the following values in the /etc/sysctl.conf
file. Run the following command:
sysctl -p /etc/sysctl.conf
Set these to 1:
net.bridge.bridge-nf-call-iptables = 1
net.bridge.bridge-nf-call-arptables = 1
9.16.4. Upgrading to XenServer 6.2 SP1 Hotfix XS62ESP1005
It is highly recommended that all XenServer clusters are upgraded to XenServer 6.2 SP1 Hotfix
XS62ESP1005. You can upgrade from any prior version of XenServer to the latest version, which
might include multiple hops as part of a single upgrade process. For example, if you are upgrading
from 6.0.2, upgrade the master host by using the upgrade path given below, followed by each slave
host upgrading to XenServer 6.2 SP1 Hotfix XS62ESP1005 by using this same upgrade path:
1. XenServer 6.0.2 to XenServer 6.2
2. XenServer 6.2 to XenServer 6.2 SP1
3. XenServer 6.2 SP1 to XenServer 6.2 SP1 Hotfix XS62ESP1005
After upgrading, ensure that XenServer Pool HA is enabled.
