Boot a UC26 pc.img in QEMU.
|
|
|
|
Options:
|
|
--img PATH Disk image (default: artifacts/images-dev/pc.img)
|
|
--stock Use stock image artifacts/images/pc.img (console-conf / Ubuntu SSO)
|
|
--ram MB RAM in MiB (default: 2048)
|
|
--smp N vCPU count (default: 2)
|
|
--ssh-port PORT Host port forwarded to guest :22 (default: 8022)
|
|
--reset-uefi-vars Recopy writable OVMF vars from host template
|
|
-h, --help Show this help
|
|
|
|
Dev image (default): SSH after first boot without Ubuntu One:
|
|
ssh -i config/ssh/smo-dev smo@localhost -p 8022
|
