Updating VM memory - Db_exn.Read_missing_uuid


Usuario Sistemas

Question

Hello, 

 

Last month we updated the servers to XCP 8.2. 

 

Today when I was revising the /var/log/xensource.log I saw this:

 

Oct  4 00:41:16 XXX xapi: [error||54 |Updating VM memory usage D:96dd0a69967d|monitor_mem_vms] Unable to update memory usage for VM 2c1a728b-6061-bae3-f71a-d88a67786720: Db_exn.Read_missing_uuid("VM", "", "2c1a728b-6061-bae3-f71a-d88a67786720")

 

The machine (as the log says), doesn't exists:

 

[15:57 XXX ~]# xe vm-list | grep -A3 2c1a728b-6061-bae3-f71a-d88a67786720        

 

 This logs repeat at every two second approximately. 

 

I don't know what to do about this machine, because the log says that they can't update the memory, but the machine doesn't exists.

 

XCP Version:

[16:03 XXX ~]#  cat /etc/redhat-release
XCP-ng release 8.2.0 (xenenterprise)

 

Thank you in advance.


Regards,
David.

You may need to destroy that old VM if the host still thinks it exists.  This KB article may help: https://support.citrix.com/article/CTX215974

 

Hello Tobias and thank you for the reply.

 

Since I did the xl destroy the log stopped showing the error:

 

[10:47 XXX ~]# list_domains | grep 2c1a728b-6061-bae3-f71a-d88a67786720
 19 | 2c1a728b-6061-bae3-f71a-d88a67786720 |    B H
[10:50 XXX ~]# xl destroy 19

Best regards,

David.
