| MySQL upgrade problems |
| ====================== |
| |
| With certain MySQL versions (see below), issues have been seen with "cloud.nics" table's |
| column type (which was not updated properly during CloudStack upgrades, due to MySQL limitations), |
| which eventually may lead to exception seen in the management server logs, causing users to |
| not be able to start any VM. |
| |
| The following SQL statement needs to be manually executed in order to fix such issue: |
| |
| .. parsed-literal:: |
| ALTER TABLE nics MODIFY COLUMN update_time timestamp DEFAULT CURRENT_TIMESTAMP; |
| |
| The issue is known to affect the following MySQL server versions: |
| |
| - 5.7.34 or later |
| - 8+ |
