keepalived master cannot reclaim virtual IP after recovered
Both servers running keepalived become masterkeepalived - service not available on the 'passive' hostkeepalived not starting and complaining about not set virtual idLVS Keepalived connection between master and backupVIP not dropping from backup keepalivedKeepalived unwanted transition to masterSet up keepalived for MySQL Master-Master replicationAWS keepalived backup immediately goes to MASTERkeepalived - Virtual is not routing my requests to real serverskeepalived doesn't detect loss of virtual IP

}
Steps
- Start both master and slave
- Keep pinging virtual ip (i.e
192.168.10.100) - Shutdown master
- Slave enters MASTER state
- Restart master
- Slave enters BACKUP state and Master enters MASTER state
Ping doesn't work after step 6. No server gets the virtual ip. (I checked with ip addr show eth1)
Master can get back the virtual ip until I restart the keepalived service.
How to make the master getting virtual ip without restart the service?

Only thing that jumps out different between your config and ones I'm using are that I have
virtual_ipaddress { <ip> dev <devname> }
That may not strictly be necessary, but that's the only difference I can see vs. a known working setup.

Your answer looks to be a good quality one, but it is not enough. Please try to formulate in round sentences, it should be understable easily (also for people with very different native language or with little knowledge on the topic).
