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.

Description Gurhan Ozen 2011-08-12 22:29:39 UTC 
Description of problem:
This is a weird issue. For example this works fine:
virt-install  --name GuestOne_nogfx --location nfs://bigpapi.bos.redhat.com:/vol/engarchive2/redhat/released/RHEL-6/6.1/Server/i386/os --ram=1024 --vcpus=1 --file-size=8 --hvm --debug --prompt --accelerate --os-variant=virtio26 --network bridge:br0 --file /var/lib/libvirt/images/GuestOne_nogfx.img --noreboot --nographics --extra-args "console=tty0 console=ttyS0,115200"

(only serial console is given, a manual installation)

However when trying to do this as an automated install with kickstart the installation basically slows down greatly , and the data on serial console chokes, sometimes a big chunk comes followed by long pause and it repeats that way. For example the command:
virt-install  --name GuestOne_nogfx --location nfs://bigpapi.bos.redhat.com:/vol/engarchive2/redhat/released/RHEL-6/6.1/Server/i386/os --ram=1024 --vcpus=1 --file-size=8 --hvm --debug --prompt --accelerate --os-variant=virtio26 --network bridge:br0 --file /var/lib/libvirt/images/GuestOne_nogfx.img --noreboot --vnc --extra-args "ks=http://lab2.rhts.eng.bos.redhat.com/cblr/svc/op/ks/system/guest-80-103.rhts.eng.bos.redhat.com console=tty0 console=ttyS0,115200"

Would take forever to install. More of then not the installation happens but the virt-install doesn't return still waiting for something. Same experience happens without the console args as well. 

This is causing issues on beaker automated tests, many tests are timing out. This started to happen in 6.1 .

Is this 100% reproducible? Still seeing this with latest 6.2 packages? Is this reproducible outside of rhts?

Can you provide virt-install --debug output from one of these runs, as well as /var/log/libvirt/qemu/$vmname.log?

I can't imagine what virt-install could do to make the install run slowly, so I'm guessing this is a qemu-kvm or anaconda issue.
Comment 4 Dave Allan 2011-10-18 13:57:48 UTC 
Gurhan, are you still seeing this?  It seems like a serious problem, but we're going to need your assitance diagnosing what's going on.
Comment 5 Gurhan Ozen 2011-10-18 20:22:44 UTC 
I am going to check it with one of the latest 6.2 trees now.
Thanks,
Comment 6 Gurhan Ozen 2011-10-18 22:53:00 UTC 
This issue no longer exists with RHEL6.2-20111018.n.0 tree:

Thanks, Gurhan.  I'm going to close as WORKSFORME, but please reopen if it reappears.  -Dave
