I deleted my port virbr0 using brctl command and now when I want to create a virtual network, it gives me this error:

Error creating virtual network: failed to run '/usr/sbin/dnsmasq --version': : Success Here is my systemlog: https://pastebin.com/xjuVnsyL

How to rectify this?

Oh, we are overwritting the actual error with something useless. The real error is: Apr 1 17:41:05 dpdk-OptiPlex-5040 libvirtd.service: 1506: error : virCommandWait:2553 : internal error: Child process (LC_ALL=C PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin /usr/sbin/dnsmasq --version) unexpected exit status 126: libvirt: error : cannot execute binary /usr/sbin/dnsmasq: Permission denied I suggest reviewing and possibly fixing permissions on dnsmasq binary (assuming libvirtd is ran as root). Or maybe there's some more info in audit.log if this is caused by SELinux. Michal
