Wang,<br>I guess you are referring to to the instance specific XML file under /etc/libvirt/qemu. It has the following section having 'vda':<br><br>===========================<br><devices><br> <emulator>/usr/bin/kvm</emulator><br>
<disk type='file' device='disk'><br> <driver name='qemu' type='qcow2' cache='none'/><br> <source file='/var/lib/nova/instances/a562a6c9-9253-4f22-8076-344e855f713d/disk'/><br>
<target dev='vda' bus='virtio'/><br> <address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/><br> </disk><br>....<br>
===========================<br>Can you specify what exactly I need to change ?<br>Thanks,<br>Nikhil<br><br><br><div class="gmail_quote">On Tue, May 14, 2013 at 1:45 PM, Wangpan <span dir="ltr"><<a href="mailto:hzwangpan@corp.netease.com" target="_blank">hzwangpan@corp.netease.com</a>></span> wrote:<br>

<div><font face="Verdana">Hello,<br>I recently installed Grizzly
(single-node) on Ubuntu 13.04 on x86 64 bit having two physical NICs. I posted
about the networking issues that I was facing after the installation in an
earlier post.<br>Well, while I was debugging the networking issue, I came across
a more serious issue -- my host machine got rebooted (power-cycle) and on reboot
I see that my two VMs are shown in "shut-off" Status and "shut-down" Power state
in the Dashboard GUI. The options available to me are only "soft reboot", "hard
reboot", "terminate instance", "Disassociate Floating IP" and "Edit Instance". I
did first "soft reboot" and the console shows "No bootable device". Then i tried
"Hard reboot" and again the same message "No bootable device".<br>I checked that
all services are running fine and there are no error messages in the logs for
nova, quantum, etc.<br><br>I followed installation instructions based on the
following link:<br><a href="https://github.com/mseknibilel/OpenStack-Grizzly-Install-Guide/blob/OVS_SingleNode/OpenStack_Grizzly_Install_Guide.rst" target="_blank">https://github.com/mseknibilel/OpenStack-Grizzly-Install-Guide/blob/OVS_SingleNode/OpenStack_Grizzly_Install_Guide.rst</a><br>
