Troubleshooting virtual machine instances
These sections describe a behavior you might encounter and provide suggested actions you can
take.
Delete instance operation only partially completes when host is unresponsive
Apply the recommendations that pertain to your situation.
Possible cause and recommendationSymptom
The Matrix KVM Admin Console has lost communication with
the server that is hosting the virtual machine instance
Deleting an instance triggers an action on both the Matrix KVM Admin
Console appliance and the host. If the host is unresponsive, deleting an
instance is only partially completed and requires manual cleanup.
You see Warning: This instance
is on a host that is not
responding
1. Click Cancel to return to the previous screen without deleting the instance.
2. Try to restore communication by rebooting the host shown in the “Hosted
on” field of the instance. If the host recovers, the instance can be cleanly
deleted using the “Delete” action on the Instances screen. A clean delete
removes the instance from both the Matrix KVM Admin Console appliance
database and the host.
3. If the host is in an unrecoverable state (on the Hosts screen, the state of
the host is “Error”), return to the Instances screen. Select the instance,
select the “Delete” action, and click Yes, delete when the warning message
is displayed.
IMPORTANT: This performs a partial delete, which removes the instance
from the Matrix KVM Admin Console appliance database but does not
remove the instance from the host. After a partial delete, you must clean
up the environment as follows:
• Manually delete all instances on the host.
• From the Hosts screen, select the host and deactivate it.
• Check the size of the log files in /var/log/nova directory and delete
them if they are consuming disk space needed for the next activation
or other use.
• Remove the server blade from the cloud. Connect to Matrix OE
infrastructure orchestration and select the Servers tab, and move the
server to the Unassigned pool.
4. Reinstall the operating system and reactivate the host, if desired.
See “Activate a host” (page 24).
