KVM --Guest Install from console

manyrootsofallevil · 02-26-2011, 02:38 PM

Hello,

I'm trying to do a complete install from console, i.e. not using VNC at all.

I have the following command:

Code:

virt-install -n test -r 1024 --vcpu=1  -l rhel6.iso --os-type='linux' --os-variant='rhel5' --network network:default --file=/var/lib/libvirt/images/test.img  --file-size=6 -x console=ttyS0

I also tried with disk instead of file.

If I try using -c rhel6.iso, nothing seems to happen

At any rate, the above command works in so far as it launches a text install, however, when I get to the installation method screen, it's not working.

if I select cd/dvd it complains about a lack of driver, and then it allows me to select from a list of all drivers.
If I try to use a hard drive, again it complains. It says that I don't have any hard drives and then it's back to mounting driver disks

Any ideas?

TIA

Not really sure what to say, you have provided a broken link (we all make typos) to essentially the man page, which contains an example that does not really apply.

Thanks for bothering to reply, but a RTFM would have been just as helpful. That's read the fine manual, btw.

At any rate, I've set up NFS on my box (host) and installed it off that source. This worked fine.

I had tried that before but the box has several vlans and I'm guessing that kvm was using the untagged nic, while my other NFS server was on one of the tagged vlans.

Installing it this way, also sets up grub so that the VM can be accessed via the console (serial console, that is), i.e. virsh console myvm, which is very nice indeed. Of course, I could have just ssh'd onto the virtual but it's a requirement to be able to access a VM's console.

Excerpt from grub.conf

Code:

serial --unit=0 --speed=9600
terminal --timeout=5 serial console

Or I could try

http://docs.redhat.com/docs/en-US/Re...ion/index.html

which I doubt will disappear

Hi,

I think the link should be:
http://www.techotopia.com/index.php/...irt-install%29

When you click the link EDDY1 supplied, you can add a closing bracket ")" to the url and it should be viewable.

Hope that helps,
Warren

EDIT: Sorry, I've just seen that EDDY1 has already posted the correct link.
