Here’s a quickie fix.
Was doing a fresh KVM install on CentOS 7, and tried to validate the install with running “virt-host-validate”, but I was getting one item failing and couldn’t find a fix. The error:
LXC: Checking if device /sys/fs/fuse/connections exists : FAIL (Load the ‘fuse’ module to enable /proc/ overrides)
The fix: just reinstall FUSE:
yum reinstall fuse -y
Problem solved:
