Please add "rd.debug" to the kernel command line and remove "rhgb" and post the logs again. Thank you!

From rdsosreport attached, looks like it includes the rd.debug, Am I missing any step?

initrd=initrd0.img root=live:CDLABEL=rhev-hypervisor7-7.2-20160913.0 rootfstype=auto ro rd.live.image rd.live.check crashkernel=256M rd_NO_MULTIPATH rootflags=ro elevator=deadline install rd.shell rd.debug max_loop=256 rd.luks=0 rd.md=0 rd.dm=0  BOOT_IMAGE=vmlinuz0 

Thanks!

Harold,

I have build RHEV-H 7.3 based on RHEL 7.3 and still the same issue when booting via USB the iso. Now we have attached logs from 7.2 and 7.3, please let me know if you need any additional data.

Thanks!

Does it help, if you add "nompath" to the kernel command line?

Yes.

It looks like this is the all famous multipath bug we see with vintage RHEV-H.

We have seen it several times before. It can not be fixed with vintage RHEV-H, because vintage RHEV-H contains a specific multipath.conf created by vdsm which is causing this issue.
