Re: [one-users] [Help] How to reboot a VM when the VM crashes?
Could you tell me how to force a hypervisor-level restart ? 2011/12/22 Hutson Betts hut...@tamu.edu Actually, the SHUTDOWN command, for both OCCI and ONE, is equivalent to pressing the power button on a computer, and once it's off, taking the hard drive and smashing it with a hammer. SHUTDOWN deletes the disk image, and transitions the VM to the DONE state. I would like to keep a VM, and it's files around, after I've issued a shutdown command. It's only after requesting DELETE that I would want the VM to be completely removed. As for the restart, you are correct. You can only force a hypervisor-level restart if the VM is in either the BOOT state or UNKNOWN state. -- Hutson Betts Computer Science and Engineering Texas AM University On Thu, 2011-12-22 at 12:10 +0800, cat fa wrote: There is an equivalent to a power button(SHUTDOWN), but there is no equivalent to a reset button. 2011/12/22 Hutson Betts hut...@tamu.edu Wait, this implies that there is no equivalent to a power button or reset button on the front of a computer? Wouldn't this should be a necessity of every VM management tool. As it stands, I can suspend/resume VMs, or I can (shutdown|cancel) VMs into a deleted state. However, there is no way to shutdown (Analogous to powered-off) a VM (External to the VM) and resume it later without loss of data.

[one-users] [help] How to connet to a virtual machine?
I successfully ran virtual machines on my host, but I could connect to them. The IP of my host is 1.185.2.21 . I bound eth0 to virbr0. I used these commands: ifconfig eth0 0.0.0.0 ( to give my eth0 a 0.0.0.0.0 IP ) ifconfig virbr0 1.185.2.21 ( to give my bridge the old IP of eth0 ) I create a virtual network in SunStone with leases like 1.185.2.22 1.185.2.23 1.185.2.24 However, When I ping my virtuial machines with any of those IPs, all thoes IPs are unreachable. My host abtains its own ip (1.185.2.21) through DHCP. Documents on Opennebula.org told me how to start a virtual machine, but it didn't tell me how to connect to a vritual machine.
