Subject: Re: [pve-devel] [PATCH docs/qemu-server/manager v17 0/10] Virtio-fs
Date: Mon, 7 Apr 2025 16:31:52 +0200	[thread overview]
Message-ID: <27d1b340-a527-4b66-929d-d7393eeab3d4@proxmox.com> (raw)
In-Reply-To: <20250407134950.265270-1-m.frank@proxmox.com>

Tested on a fresh proxmox-ve_8.4-ALPHA-1.iso install.

Configured a directory mapping and passed it to a Debian VM with the
default settings. Inside the VM I mounted the directory using
`mount -t virtiofs dirid /mnt/path`.

Writing some data to the directory from inside the VM with
`dd if=/dev/urandom of=/mnt/path/bench bs=1M` was decently fast:
190 MB/s
