Public bug reported:
If one configures more than one network to use DHCP, multiple dnsmasq
processes are started, one for each network. The problem is that each
process has --dhcp-lease-max configured for the number of leases in it's
own network. But since multiple dnsmasq processes share the standard
lease file it's possible that more leases are already in the lease file
than the newly configured network yielding an error when the new dnsmasq
tries to start:
dnsmasq: too many stored leases
Steps to Reproduce:
1. define a /24 network in libvirt
2. obtain (or simulate by populating the leases file) 30 leases
3. define a second /28 network
Actual results:
libvirtd will report:
09:46:47.004: error : virRunWithHook:857 : internal error '/usr/sbin/dnsmasq
--strict-order --bind-interfaces --pid-file=/var/run/libvirt/network/test.pid
--conf-file= --listen-address 10.0.1.1 --except-interface lo --dhcp-range
10.0.1.1,10.0.1.14 --dhcp-lease-max=14' exited with non-zero status 5 and
signal 0:
