Configuring Guest Os Interface On Cisco Ios - Cisco IR829 Hardware Installation Manual

Chapter 5 Guest Operating System (Guest OS) Installation and Configuration

Configuring Guest OS Interface on Cisco IOS

The Guest OS Ethernet port (eth0) connects to GigabitEthernet 5 on Cisco IOS. To configure the
GigabitEthernet 5 interface with the default gateway address of the DHCP pool, enter the following
commands:
Note IPv6 must always be enabled on GigabitEthernet 5.
Command
interface GigabitEthernet 5
ipv6 enable
ipv6 address 2001:DB8:FFFF:0000:0000:0000:0001
ipv4 enable
ipv4 address 9.1.2.1 255.255.255.0
no shutdown
There exists a condition where the IR829 could display slow performance if the guest OS is consuming
Note
too many CPU resources.
By default, Guest OS gets 50% of one of the cores of the CPU. The following command allows you to
change the percentage of CPU allocation to VDS out of 100. The rest will go to Guest OS. In the situation
where you don't use the Guest OS, the CPU can be allocated 90% to VDS.
For Example:
IR800>en
IR800#config t
Enter configuration commands, one per line.
IR800(config)#iox hypervisor ?
sched-policy
IR800(config)#iox hypervisor sched-policy ?

IR800(config)#iox hypervisor sched-policy 90
percentage of CPU ticks to VDS
VDS 10% Guest OS 90%
VDS 20% Guest OS 80%
VDS 30% Guest OS 70%
VDS 40% Guest OS 60%
VDS 50% Guest OS 50%
VDS 60% Guest OS 40%
VDS 70% Guest OS 30%
VDS 80% Guest OS 20%
VDS 90% Guest OS 10%
Purpose
