I had a prior private conversation with Robert last week. This particular use case will not work until PCI hotplug support is there - this is not a limitation of VirtIO (fundamentally or as implemented in FreeBSD). Workarounds include use VirtIO SCSI since it supports hot plug. In FreeBSD 10, VirtIO block supports the resize events from the hypervisor, but the GEOM support for this was not MFC'ed to 9. > sean > > _______________________________________________ > freebsd-virtualization@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-virtualization > To unsubscribe, send any mail to > "freebsd-virtualization-unsubscribe@freebsd.org" >
