check_user_quota added up the vCPUs, memory and disks of the user's VMs, but skipped a VM whose host failed a TCP probe. A host that was down therefore let users exceed their quota, and the probe always failed for ssh computes named by an ssh_config alias or reached through ProxyJump, so their VMs were never counted. A VM that could not be read turned the page into the error page instead. - Hosts are checked with Compute.status, the connection WebVirtCloud uses, once per host. A VM that cannot be read (host down, VM gone) makes the usage unknown: clone and resize up are refused with their own message (fail closed). - A request that adds nothing is not checked, so a user over quota can still shrink a VM. Users without limits, and an exceeded instance count (from the database), need no host either. - Memory resize of a running VM changes only the current memory, but the quota was charged with the submitted maximum. It is now charged with no change, and resize_mem gets the current maximum, so a VM that shuts down meanwhile cannot take an unchecked one. - The VM page no longer computes the quota on every load (it read every VM of the user on every host for a "quota reached" banner). The limit is reported when a change is refused. The test that expected a down host to pass the quota now expects it to be refused. Checked against the test hosts: with a VM behind an ssh_config alias the previous code counted 29 vCPUs, the new one 31; with a VM on an unreachable host the previous code allowed +1 vCPU, the new one refuses it after 5.1 s and allows -1 at once. The new tests fail on the previous code, except the ones guarding unchanged behaviour. |
