Subject: [pve-devel] [PATCH docs/qemu-server 0/2] Ballooning/PCI passthrough incompatibility: add warning and docs
Date: Mon, 13 Nov 2023 18:09:14 +0100	[thread overview]
Message-ID: <20231113170916.184994-1-f.weber@proxmox.com> (raw)

When using PCI(e) passthrough, enabling ballooning for a VM (as in, setting a
"minimum memory" amount that is smaller than "memory") does not have any
effect, which may be surprising to users [0].

Patch #1 adds a note about this incompatibility to the PCI(e) passthrough and
ballooning sections of the docs.

Patch #2 implements a warning on VM start if PCI(e) passthrough and
ballooning are both enabled.
