Subject: [pve-devel] [PATCH qemu-server v2 3/4] vmstatus: switch mem stat to PSS of VM cgroup
Date: Wed,  9 Jul 2025 18:37:00 +0200	[thread overview]
Message-ID: <20250709163703.2540012-21-a.lauterer@proxmox.com> (raw)
In-Reply-To: <20250709163703.2540012-1-a.lauterer@proxmox.com>

Instead of RSS, let's use the same PSS values as for the specific host
view as default, in case this value is not overwritten by the balloon
info.
