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.

Important: if this rebase instead contains *only bug fixes,* or *only enhancements*, select the correct option from the Doc Type drop-down list. Rebase package(s) to version: Highlights, important fixes, or notable enhancements: OS dependent data is not maintained by virt-manager but it is read from libosinfo and this will allow better default values (RAM size, storage size, #CPUs) according to the OS chosen at installation time.

Comment 2 zhengqin 2014-02-18 08:33:17 UTC 
Could reproduce it on latest RHEL7 with virt-manager-0.10.0-16.el7.noarch.

Steps to Reproduce:
1. Create a VM for vista select OS type as "Windows" and version as"Microsoft Windows vista",forward to create a disk image.
2. the default disk image is 8G,but vista install needs at least 15G,if we create VM with the default setting,install will fail
Comment 5 CongDong 2014-09-10 08:25:38 UTC 
I can reproduce with:
virt-manager-0.10.0-20.el7

VERIFY:
with  virt-manager-1.1.0-1.el7.noarch

Steps:
1. open virt-manager
#virt-manager
2. Click "Create  a new virtual machine"
3. In step 2, choose os type and version
os type: windows
version: Microsoft windows vista
4. in step 4, check the default disk size.


Result:
The default size is 40G

I test with win8 and win7 too, the default size is also 8G, it's not enough for the installation.

As the result, I think should update other os metadata

So, set ASSIGNED.
Comment 6 Giuseppe Scrivano 2014-09-10 12:23:52 UTC 
please create a new bug and assign it to libosinfo.  This kind of problems should now be reported to libosinfo and not to virt-manager as libosinfo is the owner of the OS database.

virt-manager is only responsible for reading correctly this information from libosinfo, you can check if it is correct by looking at the file /usr/share/libosinfo/db/oses/windows.xml

I check the file, but the storage is not the default size in virt-manager:
# cat /usr/share/libosinfo/db/oses/windows.xml
...
  <os id="http://microsoft.com/win/8">
    <short-id>win8</short-id>
...
    <resources arch="i686">
      <minimum>
        <cpu>1000000000</cpu>
        <n-cpus>1</n-cpus>
        <ram>1073741824</ram>
        <storage>17179869184</storage>
      </minimum>
    </resources>

    <resources arch="x86_64">
      <minimum>
        <cpu>1000000000</cpu>
        <n-cpus>1</n-cpus>
        <ram>2147483648</ram>
        <storage>21474836480</storage>
...

As the result win8 storage need 16G for win8 and 20G for x86_64. 
But in virt-manager the default is still 8G for win8.
Do you think it's still a problem for libosinfo?
Comment 8 Giuseppe Scrivano 2014-09-12 08:32:20 UTC 
virt-manager reads the "recommended" resources block and win8 misses this information.  I'll propose a change in virt-manager to consider the "minimum" information where the "recommended" is missing.
Comment 9 Giuseppe Scrivano 2014-09-12 09:04:35 UTC 
I've proposed a patch upstream to consider "minimum" resources when "recommended" is missing:

Comment 12 CongDong 2014-09-18 07:54:43 UTC 
I re-test with :
virt-manager-1.1.0-2.el7

Steps are same with comment 5.

virt-manager reads the recommended default.
If the recommended is missing, the value is double of the minimum,
test with win2k3r2, win2k3, win7, win8 and win8.1

Also test rhel7 and rhel6, default value is same with usr/share/libosinfo/db/oses/rhel.xml.

As this result, move to verify.
