There is a known issue about netconsole does not support in vlan network in 5.5. (http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Virtualization_for_Servers/2.2/html/5.5-2.2_Hypervisor_Release_Notes/sect-Release_Notes-Known_Issues.html) But I can see the output on netconsole server after configure netconsole in 5.7(see attached file "nc"), so I don't think that know issue still exists in 5.7. after configure netconsole, please reboot twice if did not met the hang issue at the first time. It not regression bug , test on 5.7-20110824.0 and 5.7-20110725.1, both can reproduce this issue. The same issue occurs in rhev-hypervisor-5.8-20111019.0.el5. |
