Re: [Xen-users] Xen rebuild and install

Get it, thanks very much.

Since I need to modify hypervisor's timer related code. So a reboot is required :(

It's not necessary to build Xen in bare metal - it still has access to write to the disk in dom0.

Whether there's a faster way of doing it depends on what you're modifying. If it's Xen itself then a reboot is required to modify. If a daemon or utility you may be able to restart just that.

The other alternative is to run Xen inside itself or another VM, assuming it supports nested SLAT/EPT. It'll probably be faster to reboot a VM than the host system.

Beyond that, buy an SSD?
