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 of problem:
error message need be improved for q35 guest with pci-root controller, and for other machines guest with pcie-root controller
Version-Release number of selected component (if applicable):
qemu-kvm-1.5.3-2.el7.x86_64
libvirt-1.1.1-3.el7.x86_64
How reproducible:
100%
Steps to Reproduce:
1. define a guest will machine='q35'.
2. edit guest xml:
from
"<controller type='pci' index='0' model='pcie-root'/>
"
to
"<controller type='pci' index='0' model='pci-root'/>
"
and save.
3. edit guest xml:
from
"machine='pc-q35-rhel7.0.0'"
to
"machine='pc'"
and save.
Actual results:
2. # virsh edit test1
error: XML error: PCI bus is not compatible with the device at 0000:00:02.0. Device requires a PCI Express slot, which is not provided by bus 0000:00
Failed. Try again? [y,n,f,?]:
3. # virsh edit test1
error: internal error: PCI bus is not compatible with the device at
0000:00:01.0. Device requires a standard PCI slot, which is not provided by
bus 0000:00
Failed. Try again? [y,n,f,?]
Expected results:
2. # virsh edit test1
error: XML error: A q35 machinetype shouldn't have a pci-root controller.
Failed. Try again? [y,n,f,?]:
3. # virsh edit test1
error: XML error: A not q35 machinetype shouldn't have a pcie-root controller.
Failed. Try again? [y,n,f,?]:
Additional info:
