Subject: bug#47225: QEMU warning about performance
Date: Thu, 18 Mar 2021 02:25:26 -0400 [thread overview]
Message-ID: <YFLyVjT+hOYHvMS2@jasmine.lan> (raw)
While using `guix system vm`, I noticed this warning. I think it's new,
maybe from the 5.2.0 update?
------
qemu-system-x86_64: warning: 9p: degraded performance: a reasonable high msize should be chosen on client/guest side (chosen msize is <= 8192). See https://wiki.qemu.org/Documentation/9psetup#msize for details.
------
That web page suggests that we increase the virtio packet size when
declaring the 9p file-systems, I think in %linux-vm-file-systems of (gnu
system vm).
