Cisco IR829 Integrated Services Router Hardware Installation Guide
Chapter 5 Guest Operating System (Guest OS) Installation and Configuration
Configuring Cisco IOS
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.
Note
There exists a condition where the IR829 could display slow performance if the guest OS is consuming
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. End with CNTL/Z.
IR800(config)#
iox hypervisor ?
sched-policy percentage of CPU ticks to VDS
IR800(config)#
iox hypervisor sched-policy ?
10 VDS 10% Guest OS 90%
20 VDS 20% Guest OS 80%
30 VDS 30% Guest OS 70%
40 VDS 40% Guest OS 60%
50 VDS 50% Guest OS 50%
60 VDS 60% Guest OS 40%
70 VDS 70% Guest OS 30%
80 VDS 80% Guest OS 20%
90 VDS 90% Guest OS 10%
IR800(config)#
