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 zhanghaiyan 2010-05-14 05:54:35 UTC 
Description of problem:
virt-install doesn't provide any parameter to set guest machine type, which causes all guest xml config file use default value 'machine='rhel6.0.0'' 

Version-Release number of selected component (if applicable):
- kernel-2.6.32-25.el6.x86_64
- python-virtinst-0.500.3-2.el6.noarch
- qemu-kvm-0.12.1.2-2.53.el6.x86_64
- qemu-img-0.12.1.2-2.53.el6.x86_64
- libvirt-0.8.1-3.el6.x86_64


How reproducible:
Always

Steps to Reproduce:
1. # virt-install -n rhel55-i386 -r 2048 -l http://download.englab.nay.redhat.com/pub/rhel/released/RHEL-5-Server/U5/i386/os/ -f /var/lib/libvirt/images/rhel55-i386.img

Creating domain...  
2. # virsh dumpxml rhel55-i386
<domain type='kvm' id='2'>
  <name>rhel55-i386</name>
  <uuid>41fdcbb2-f6cf-cb03-e6c8-203e48cc0d9b</uuid>
  <memory>2097152</memory>
  <currentMemory>2097152</currentMemory>
  <vcpu>1</vcpu>
  <os>
    <type arch='x86_64' machine='rhel6.0.0'>hvm</type>
................
  
Actual results:
Because no parameter to set guest machine type, rhel55 guest is defined as machine='rhel6.0.0' defautly. 

Expected results:
Provide parameter to set guest machine types, and give some value example:
# /usr/libexec/qemu-kvm -M ?
Supported machines are:
pc-0.12    Standard PC
pc-0.11    Standard PC, qemu 0.11
pc-0.10    Standard PC, qemu 0.10
isapc      ISA-only PC
pc         RHEL 6.0.0 PC (alias of rhel6.0.0)
rhel6.0.0  RHEL 6.0.0 PC (default)
rhel5.5.0  RHEL 5.5.0 PC
rhel5.4.4  RHEL 5.4.4 PC
rhel5.4.0  RHEL 5.4.0 PC

Additional info:
The same problem also appears when using python-virtinst to import a image to generate a guest
Comment 2 RHEL Program Management 2010-05-14 07:31:15 UTC 
This feature request did not get resolved in time for Feature Freeze
for the current Red Hat Enterprise Linux release and has now been
denied. You may re-open your request by requesting your support
representative to propose it for the next release.
Comment 3 Daniel Berrangé 2010-05-14 09:53:36 UTC 
Exposing it in virt-install is reasonable, but I think we should be wary of exposing machine type in the UI for virt-manager since I think it will seriously confuse users. With machine types like 'rhel-5.4.0', people will very likely think they should be making this match the OS version of their guest, when in fact this is refering to the host ABI & nothing todo with guest OS.
Comment 5 Cole Robinson 2010-06-22 14:36:46 UTC 
Not sure why this is marked as 6.0, it's not hugely important IMO. Moving to 6.1
Comment 7 Cole Robinson 2010-12-07 15:00:59 UTC 
--machine options added for virt-install:

http://hg.fedorahosted.org/hg/python-virtinst/rev/6d0e9e6adda1

Maybe for virt-manager we can only expose the machine type if using a non-intel arch.
