Route bulk IPv4 to KVM VM

Bashed · 10-05-2016, 09:19 AM

Hey folks,

I'm using SolusVM for creating and administrating VMs. Unfortunately there's no option to assign bulk IPs in one shot to VMs, whether OVZ or KVM platform. You literally have to add single IPs one at a time, from a drop down menu.
I searched around and apparently there's a possible way to add bulk IPs to a KVM VM, but not 100% sure how to go about this. I would appreciate a simplified explanation on how I can do this.

I tried one tutorial and have it somewhat halfway through.

Example, KVM Node: Assigned a single /24
5 KVM VMs created. I want to add a /26 in one shot to one of the VMs. How? I'm running Centos 6.8 64bit on the NODE.

/etc/sysconfig/network

Code:

NETWORKING=yes
HOSTNAME=server.domain.net
GATEWAY=br1

/etc/sysconfig/network-scripts/ifcfg-eth0

Code:

DEVICE=eth0
ONBOOT=yes
BRIDGE=br0
HWADDR=b8:ac:6f:65:31:e5

/etc/sysconfig/network-scripts/ifcfg-br0

Code:

DEVICE=br0 TYPE=Bridge
BOOTPROTO=static 
ONBOOT=yes 
IPADDR=xxx.xxx.22.70 
NETMASK=255.255.255.0 
DELAY=0

You could use the virt-edit command at the hostOS to edit the IPADDR line for earch VM using bash/sed in a loop.
That's what I used to do before learning how to use Ansible.

Could you please explain? Commands to run?

virt-edit command in a for loop does the trick.

Honestly, I have no idea what you're saying. I know CLI just fine, but you're not being clear on the actual command.

Would appreciate help on this.
