    Migrate doesn't check target host memory

    When target host doesn't have enough free memory, migration process doesn't stop. It tries to allocate memory on the target host, which result in OOM killing the largest VM, and another, and another. In earlier versions of Proxmox VE it wasn't like that. Migration was giving an error "cannot...

Therefore, smaller backups writes faster and take less space. But recently I discovered that restore uses gzip, not pigz (you can see...

If there is one comment with non-ASCII characters, all rules disappear, including rules with strictly ASCII comments (although they stay in configuration, just don't display). It happens even if comment's language is the...
