[libvirt] [PATCH 0/2] qemu: Limit backing chain to max 200 layers (blockdev-add saga)

Posted by Peter Krempa 2 weeks ago
More than 256 deep element tree break with our XML parser. Backing
chains are one of the simple ways to get there. Forbid them. Note that
the practical limit/sane approach is way less than 200.

Peter Krempa (2):
  qemu: domain: Refactor cleanup in qemuDomainDetermineDiskChain
  qemu: Prevent storage causing too much nested XML
