Jan 14 2008, 11:43 PM EST Hi team, is this possible to create multiple Linux virtual machines on the USB disk? My laptop has the limited disk space for the current windows OS, so I would like to attach a single 500 gb drive "through USB port", which will be partitioned into 100 gb each (5 partitions), and make five virtual machines installing the Linux OS into "the partitions on the USB attached disk." My intention is I would like to use my laptop's cpu, memory and network (not disk) for the Linux virtual machines only when I plug in the USB disk into the laptop. I like to operate just a Window virtual machine on my laptop while I don't plug-in the USB drive. Not sure if it's possible. 2 out of 13 found this valuable. Do you? |

Feb 17 2008, 9:25 PM EST Hi, I'm wondering if you attach this disk for a full-virtualized vm or a para one? if you are using the HVM,please check its vm.cfg to see if your newly attached shared virtual disk has appeared in that config file,if so,issue 'fdisk -l' in vm box to see its existence. **As for HVMs,please NOTE that there are four IDE disks are allowed to be attached to them at most(including the CDROM and shared disks).so please check your vm.cfg to see if your configuration has exceeded such limitation. 0 out of 8 found this valuable.

Feb 22 2008, 4:48 PM EST I have played with this and there are two problems with your logic. First, you can't really run a Windows VM on your laptop and see the console on the laptop display. You need to have an X-Window environment installed to make this happen. The current implementation of dom-0 prohibits this because it is a trimmed down Linux with no X11. When you switch to dom-xyz you get a command line interface and not a windowed interface to bring up a console and vnc. The second problem is that partitioning a 500G disk into 100G segments really does not solve anything. You would need to somehow map the USB disk which will typically come up as /dev/sda on a laptop into the running_pool and use it to create virtual guest operating systems (either paravirtualized or hardware virtualized depending upon your laptop). I have played with this and got it working. I use the USB disk not for the guest operating image but the iso_pool and seed_pool because the USB disk is very slow compared to the internal disk. I would rather have the running_pool on the local disk and the stuff that I don't use very much on the slower one. I do understand the problem of having an 80G internal disk and a 500G USB disk. It would just be much nicer if you could attach it with firewire instead of USB. 0 out of 5 found this valuable. Do you? |
