KVM Virtualization in RHEL 6 Made Easy

# restorecon -R -v /vm-images

Verify that the context was changed:

# ls –aZ /vm-images

drwxr-xr-x. root root system_u:object_r:virt_image_t:s0 .

dr-xr-xr-x. root root system_u:object_r:root_t:s0 ..

5. If you are going to export the directory /vm-images as a samba or NFS share, there are SELinux

Booleans that need to be set as well:

# setsebool -P virt_use_samba 1

# setsebool -P virt_use_nfs 1

3. Creating VMs

Installation of VMs using the virt-install tool is very straight-forward. This tool can run in interactive or

non-interactive mode. Let‟s use virt-install in non-interactive mode to create a RHEL 6.1 x64 VM named

vm1 with one virtual CPU, 1 GB memory and 10 GB of disk space:

# virt-install \

--network bridge:br0 \

--name vm1 \

--ram=1024 \

--vcpus=1 \

--disk path=/vm-images/vm1.img,size=10 \

--graphics none \

--location=http://my.server.com/pub/rhel6.1/install-x86_64/ \

--extra-args="console=tty0 console=ttyS0,115200"

 --network bridge:br0

If you created a network bridge (as specified in Chapter I, steps 6-10) and want to use it for full

inbound and outbound connectivity, then you must specify it.

 --name vm1

No big mystery here, this is the name of the VM

 --ram=1024

This is the amount of memory in the VM in MBs

 --vcpus=1

You guessed it, this is the number of virtual CPUs

 --disk path=/vm-images/vm1.img,size=10
