You could set up NAT with each guest on its on private network. First, you'd need to stop bridging all of their network interfaces together (after all, if they're all on the same switch, they're hardly on their own private networks). Then you'd set up NAT rules, and maybe it'd work. But probably not—the outgoing path should work, but the return path is a ...


have you check forwarding option ? sysctl net.ipv4.ip_forward try sysctl -w net.ipv4.ip_forward=1 note that unless told otherwise unix host do not forward from one interface to another. my thanks goes to http://www.ducea.com/2006/08/01/how-to-enable-ip-forwarding-in-linux/


Simple answer: no. What you're trying to do is, from a networking perspective, identical to trying to have multiple physical hosts with the same IP. It won't work.


They're space-consuming. If you write 10% to a logical volume and then take a snapshot, the other 90% of that volume become unusable. Uh, no it isn't. The LVM snapshot presents two block devices, the origin LV (what you're snapshotting) and the snapshot LV. Only data that changes on either LV is actually written to the snapshot LV. You can mount the ...


To complete @Lambert's answer, there is also Btrfs (a linux file system) which allows to create and restore snapshots of subvolume of the file system. For differences between the two read this post on reddit. Btrfs is included into the linux kernel, and you can use it a you root filesystem. It seems possible to boot on it. Regarding to its "experimental" ...


Virtualbox allows to configure two types of SCSI controllers, one being LSILOGIC the other Buslogic compatible. Those should be supported by the bt(4) and mpt(4) drivers. You can remove all other SCSI controllers If you use IDE/SATA controllers you can remove all SCSI drivers.


I'm not a grub2 expert (sorry) but try adding --skip-fs-probe to your grub-install line, I have found this prevents creation of /boot/grub/device.map which can cause booting to a grub prompt. I think that without this parameter grub-install, instead of doing what you tell it, thinks it is cleverer than you, and may do something different. Another thing is ...
