I had to use the upstream qemu to get the filesystem passthrough to be enabled. I have another question: I would like to always include and automate a standard stanza in newly created libvirt XML domain definition of a VM. For example, <filesystem type='mount' accessmode='passthrough'> <source dir='/var/tmp/shareme1'/> <target dir='hostshare1'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/> </filesystem> Is there a way, a qemu configuration or a libvirt config, to automate including this stanza in all newly created VMs? ~Lawrence -----Original Message----- From: Cole Robinson [mailto:crobinso@xxxxxxxxxx] Sent: Thursday, September 03, 2015 1:36 PM To: Sorrillo, Lawrence; 'virt-tools-list@xxxxxxxxxx' Subject: Re: "Grey-out" Filesystem add hardware option in virt-manager in RHEL7.1 - kernel 3.10.0-229.11.1.el7.x86_64 On 09/02/2015 01:53 PM, Sorrillo, Lawrence wrote: > Hello, > > > > I was wondering about virt-manager support for the file-sharing option between > host and guest in RedHat, CentOS and Fedora. > > > > This appears to be grey out and a complaint about the inability of the > installed combination of > > libvirt and qemu to support this option is displayed.

I think even if you attached the XML to your libvirt config, qemu would fail to start because it's compiled out, but I haven't verified. - Cole _______________________________________________ virt-tools-list mailing list virt-tools-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/virt-tools-list
