For me, I usually delete this line in <device> tags * <address type='pci' domain='0x0000' bus='0x00' slot='0x08' function='0x0'/>*
Don't delete the <address> tag inside the <source>. I usually delete this line, this line means the virtual address that pass-throughed device will set in VM. And it will not get error if you save XML file, it will generate automatically while VM started. So that u don't have to worry about virtual address conflicts. 2016-02-23 4:58 GMT+08:00 Eric Griffith <egriffit...@gmail.com>: > > On Thu, Jan 28, 2016 at 8:47 PM, Stewart Adam <maill...@diffingo.com> > wrote: > >> On 2016-01-21 12:32 PM, Eric Griffith wrote: >> >>> >>> On Jan 17, 2016 16:10, "Stewart Adam" <maill...@diffingo.com >>> <mailto:maill...@diffingo.com>> wrote: >>> > >>> > On 2016-01-17 1:27 PM, Eric Griffith wrote: >>> >> >>> >> On Jan 17, 2016 13:15, "Stewart Adam" <maill...@diffingo.com >>> <mailto:maill...@diffingo.com> >>> >> <mailto:maill...@diffingo.com <mailto:maill...@diffingo.com>>> >>> wrote: >>> >> > >>> >> > On 2016-01-07 11:30 AM, Eric Griffith wrote: >>> >> >> >>> >> >> My problem is..
