I've found an upstream bug report that is very similar to what we're seeing here, so I've left a comment telling the libvirt maintainers that Guix is also seeing a similar issue: https://bugzilla.redhat.com/show_bug.cgi?id=3D1751120 In the meantime, should we revert to version 5.4.0 in Guix? I'm not sure if there are any security vulnerabilities between 5.4.0 and the most recent release, but this bug is currently preventing me from creating any VMs at all in Guix using virt-manager, which is pretty bad. =2D-=20 Chris --=-=-= Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAEBCAAdFiEEy/WXVcvn5+/vGD+x3UCaFdgiRp0FAl2IRqcACgkQ3UCaFdgi Rp2TYw/8CO/v9eUxUp21mG6u13IhxOgGv8exq56SqEIOltooiJUUTl5XQYeGPl6P bvAY/GBWSYIjrE6lwLFEvjoAqz0/I7VjzKPBwIAPkLAQyBVuIbjgMrWp5T0Rz5oI 3KmhgCgFnOGOb21SfUZ+pcLN2nSGViUugs1c/v/oNIeD6QkSPLgrEkklFoBYfbBT NhaFHEPlUnS7QIZ0Jp/SJHy8sNL9hYwQgu7CXILOx2Jj22061MmQfq1xsPUT5+B4 BpBM0e0cfid8qkEZrC+VS9n/KIoCqLwta1acPueXNHyKxADENo1/5A15TcmZ3Xew j4j0CKUXfuYzYOymjA2AoLQrtVwHAA1lnRAnJ81S8tZNwnHVQEvFOiemFRkB0xxX K4kAGOYEjnxhwJSKVl9zx4SCEAnyovTVjYZQ5ryT1YTIpnqtBT3Tqp5klmXMUmUX E0P352usyLCHkGynA1H+WjWWJZ+opigxIeitPLb0hI/kakVYASD7uhAAKTUw9vC5 ipiJDx/0YMsHzTg/2Nnezvi5nCXlilRRiVuV04goaLk/E4aqloA31CCUDg3rk+0k OMAsw/G9qcJGXMbD2LEWGoOWA2+gxsL6xjXPTSNSJvMv29iL7t+S6Uzv5heAmWO/ jLYjHkpdpeRTAfIVF/aAVt4D7Wlpnme3+JIQOwbZnJC3ExgqD0Q= =IcTc -----END PGP SIGNATURE----- --=-=-=--
