[pve-devel] [PATCH qemu-server v17 4/10] migration: check_local_resources for virtiofs

Subject: [pve-devel] [PATCH qemu-server v17 4/10] migration: check_local_resources for virtiofs
Date: Mon,  7 Apr 2025 15:49:44 +0200	[thread overview]
Message-ID: <20250407134950.265270-5-m.frank@proxmox.com> (raw)
In-Reply-To: <20250407134950.265270-1-m.frank@proxmox.com>

add dir mapping checks to check_local_resources

Since the VM needs to be powered off for migration, migration should
work with a directory on shared storage with all caching settings.
