## Quickly launch a qemu vm with local qcow as hard drive
|
||
|
|
|
||
|
|
In this example I am using the docker0 bridge because I do not want to have to modify my shorewall config, but any proper bridge would do :
|
||
|
|
{{< highlight sh >}}
|
||
|
|
ip tuntap add tap0 mode tap
|
||
|
|
brctl addif docker0 tap0
|
||
|
|
qemu-img create -f qcow2 obsd.qcow2 10G
|
||
|
|
qemu-system-x86_64 -curses -drive file=install65.fs,format=raw -drive file=obsd.qcow2 -net nic,model=virtio,macaddr=00:00:00:00:00:01 -net tap,ifname=tap0
|
||
|
|
qemu-system-x86_64 -curses -drive file=obsd.qcow2 -net nic,model=virtio,macaddr=00:00:00:00:00:01 -net tap,ifname=tap0
|
||
|
|

The first qemu command runs the installer, the second one just runs the vm.

## Launch a qemu vm with your local hard drive
|

|

My use case for this is to install openbsd on a server from a hosting provider that doesn't provide an openbsd installer :
|
||
|
|
{{< highlight sh >}}
|
||
|
|
qemu-system-x86_64 -curses -drive file=miniroot65.fs -drive file=/dev/sda -net nic -net user
|
||
|
|
