Subject: [pve-devel] [PATCH qemu-server] qmeventd: flush after verbose printing
Date: Tue, 24 Nov 2020 15:04:06 +0100	[thread overview]
Message-ID: <20201124140406.833-1-d.csapak@proxmox.com> (raw)

if one would try to use -v in a systemd service, systemd would disable
line buffering for stdout and no output would happen (until the buffer
is full)
