Enabling Paravirtualization
To enable Paravirtualization:
The example below works on RHEL6.* or RHEL7.* without a Network Manager.
Create a bridge.
vim /etc/sysconfig/network-scripts/ifcfg-bridge0 DEVICE=bridge0 TYPE=Bridge IPADDR=
12.195
.15.1
NETMASK=255.255
.0.0
BOOTPROTO=static
ONBOOT=yes NM_CONTROLLED=no DELAY=0
Change the related interface (in the example below bridge0 is created over eth5).
DEVICE=eth5 BOOTPROTO=none STARTMODE=on HWADDR=
00
:02
:c9:2e:66
:52
TYPE=Ethernet NM_CONTROLLED=no ONBOOT=yes BRIDGE=bridge0Restart the service network.
Attach a bridge to VM.
