A tracker to track that the dhcp bug we are seeing in RHEV-H 7.0 (see dependency bug) is also getting fixed in RHEV-H.
checked Bug 1187244 - [RHEL 7.0 + 7.1] Host configure with DHCP is losing connectivity after some time - dhclient is not running The bug 1187244 is targeted to rhev 3.5.1, so this rhevh testonly bug also need to target to rhev 3.5.1 to test it in rhevh side. Thanks.
Tested this bug is fixed on following version # rpm -q ovirt-node kernel vdsm dhclient systemd ovirt-node-3.2.2-3.el7.noarch kernel-3.10.0-229.1.2.el7.x86_64 vdsm-4.16.13.1-1.el7ev.x86_64 dhclient-4.2.5-36.el7.x86_64 systemd-208-20.el7_1.2.x86_64 # cat /etc/rhev-hypervisor-release Red Hat Enterprise Virtualization Hypervisor 7.1 (20150420.0.el7ev) Test steps: 1. Installed rhevh 7.1. 2. Setup dhcp network via rhevh tui. 3. register to rhevm 3.5.1-0.4.el6ev 4. connect nfs storage. 5. Setup VMs running on it. 6. Wait 24hrs to check the rhevh 7.1 IP and status. 7. Wait 36hrs to check the rhevh 7.1 IP and status. Results: After 24hrs and 36hrs, the rhevh 7.1 host did not lose ip connectivity. And rhevh 7.1 is UP in rhevm portal, VMs are running as well.
This bug will be fixed in the next release, see also bug 1204782.
