+ | ===== Using Qemu from Unprivileged Users ===== | ||
+ | Using root for doing your everyday tasks is commonly discouraged so let's see how we can work around using qemu from unprivileged users. | ||
+ | Some say that it's sufficient to give sudo execution on / | ||
+ | |||
+ | User_Alias QEMUERS = al, john, jack | ||
+ | | ||
+ | Cmnd_Alias QEMUCMD = / | ||
+ | | ||
+ | QEMUERS ALL=(ALL) NOPASSWD: QEMU | ||
+ | |||
+ | This would be sufficient to run the VMs as any of the unprivileged users in QEMUERS user alias (al, john, jack) but the management script would need to run sudo qemu-system-* .... this is easy to obtain: | ||
+ | |||
+ | [ $(/ | ||
+ | eval $(echo "$CMD &" | ||
+ | |||
+ | Alternatively you could give privileges to execute the management script as root. | ||

Here are examples of the dialogs that user would see wile creating, starting, stopping and deleting a VM. | Here are examples of the dialogs that user would see wile creating, starting, stopping and deleting a VM. | ||
