Hi all
We are using oVirt engine 3.5.1-0.0 on Centos 6.6
We are deploying two hosts with vdsm-4.16.10-8.gitc937927.el7.x86_64
No hosted-engine, it run on a dedicates VM, outside oVirt.
Behavior: PXE boot of a VM, ends in timeout (0x4c106035), instead to accept=
the DHCP offer coming from DHCP server.
Tcpdump capture started on the vdsm host, bond0 interface shows clearly tha=
t DHCP offers reach the vdsm interfaces three times before PXE client ends =
in timeout.
Incoming DHCP offer is correctly tagged when it comes to the bond0 interfac=
e and forwarded to the bond0.bridge interface.
PXE simply ignore it. PXE version is gPXE 0.9.7.
bond0.bridge interface is already setup with STP=3Doff and DELAY=3D0.
If we install a VM using command line boot parameters, VM install & run fi=
ne. The issue is only related to PXE process, when it is expected to use th=
e DHCP offer.
I can provide tcpdump capture, but I've not attached to the email because I=
'm quite new of the community and don't know if it is allowed/correct.
On another host, under the same engine, running vdsm-4.16.12-7.gita30da75.e=
l6.x86_64 on Centos6.6, this behavior is not happening, everything works fi=
ne.
Any idea/suggestion/further investigation ?
Thanks for attention
