RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Comment 7 Eduardo Habkost 2011-09-09 19:25:34 UTC 
It looks like the guest is loading an option ROM from the NIC. I don't know if there's a way to disable that in the hardware itself or on some device-assignment command-line option. Reassigning to Don so he can take a look.
Comment 8 Don Dutile (Red Hat) 2011-09-09 19:48:53 UTC 
Is the qemu-kvm cmdline handcrafted, or is it the log of what virsh create generates with a defined guest.xml ?

Please provide guest.xml definition file (virsh dumpxml <guestname>).
Comment 9 Alex Williamson 2011-09-09 20:38:33 UTC 
rombar=0 option for pci-assign will skip loading the physical option rom.
Comment 10 Don Dutile (Red Hat) 2011-09-09 22:00:58 UTC 
Well, I see this in the cmdline too:

-boot order=c

maybe it should be =1 or =0 ?

It is handcrafted.

Yes, after adding rombar=0, this issue disappeared

I don't follow you here, what do you mean?
Comment 14 Don Dutile (Red Hat) 2011-09-13 11:59:10 UTC 
Look at the qemu-kvm cmdline you provided in Description:

# /usr/libexec/qemu-kvm -M rhel6.2.0 -enable-kvm -m 4096 -smp
4,sockets=1,cores=4,threads=1 -name rhel6.1.z -uuid `uuidgen` -rtc
base=utc,clock=host,driftfix=slew -boot order=c,menu=on -drive
                                  ^^^^^^^^^^^^^


setting boot order to 'c'; shouldn't it set it to the order number,
which would be 1 if it starts counting at 1, or 0 if 0-based indexing
used.
Comment 15 Chao Yang 2011-09-14 02:18:48 UTC 
I removed "order=c" option, and added "bootindex=1" to disk image, issue exists
Comment 16 Don Dutile (Red Hat) 2011-09-14 20:09:45 UTC 
for my sanity, could your provide the entire qemu-kvm cmdline used to start the guest? thanks.

Comment 18 Don Dutile (Red Hat) 2011-09-27 20:56:49 UTC 
c#9 and c#12 list the solution -- rombar=0 must be added.

If reporter agrees, please close this bz;
if not, please indicate why it does not.
Comment 19 Chao Yang 2011-09-28 02:32:06 UTC 
According to Comment #12, closing as WORKSFORME
