Description of problem: When trying to create a new guest I get the above error. Version-Release number of selected component (if applicable): [root@tst063 ~]# rpm -q virt-install virt-install-1.4.3-1.fc27.noarch [root@tst063 ~]# rpm -q virt-manager virt-manager-1.4.3-1.fc27.noarch [root@tst063 ~]# rpm -q libvirt libvirt-3.7.0-2.fc27.x86_64 How reproducible: 100% Steps to Reproduce: 1. Install Fedora-Server-dvd-x86_64-27-20171017.n.0.iso 2. # virt-install --hvm -l /images/Fedora-Server-dvd-x86_64-27-20171017.n.0.iso.iso --initrd-inject=/root/rawhide-64-hvm-kvm-guest.ks --extra-args "console=ttyS0,115200 vnc ip=dhcp ks=http://192.168.106.1/rawhide-64-hvm-kvm-guest.ks" --graphics vnc,listen=0.0.0.0,port=5901 --video vga --serial file,path=/root/rawhide-64-hvm.serial --ram 8192 --disk /dev/fedora_tst063/rawhide-64-hvm --name rawhide-64-hvm --network=bridge=switch,mac=C0:EB:24:DE:56:B7 ERROR Error validating install location: Validating install media '/images/Fedora-Server-dvd-x86_64-27-20171017.n.0.iso.iso' failed: Could not start storage pool: cannot open volume '/images/EFI': Transport endpoint is not connected 3.

So /images is NFS it seems. The 'transport endpoint is not connected' error seems weird here, I wonder if NFS is acting up. are you still seeing this?
I played with setsebool for xen_use_nfs or virt_use_nfs and having it on or off did not make any change.

In those last examples the root directory changing /images -> /images_nfs, and the error message changed 'transport not connected' (from libvirt) to file non-existent. Can you provide ls -lZ for /images_nfs

Insterestingly, removing /isos/lost+found fixed it in my case. So apparently, it's a case of libvirt trying too hard to open subdirectories.
Sounds like libvirt should ignore the error in this case and continue on, we do that for several other conditions for volume probing IIRC

And it seems to be related to NFS as I couldn't reproduce it with a local directory.
Thank you for reporting this issue to the libvirt project. Unfortunately we have been unable to resolve this issue due to insufficient maintainer capacity and it will now be closed. This is not a reflection on the possible validity of the issue, merely the lack of resources to investigate and address it, for which we apologise. If you none the less feel the issue is still important, you may choose to report it again at the new project issue tracker https://gitlab.com/libvirt/libvirt/-/issues The project also welcomes contribution from anyone who believes they can provide a solution.
