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.

volume info in guest

Description of problem:
Install win2019 guest with ovmf and try to get file system info via qemu guest agent,but find the file system of system reserve volume is not correct.

Version-Release number of selected component (if applicable):
mingw-qemu-ga-win-100.0.0.0-3.el7ev

How reproducible:
100%

Steps to Reproduce:
1.boot up win2019 guest with ovmf.
2.check volum info in guest.
 wmic volume list /format:hform >> volume_info.html

volume_info.html is in attachment.

3.issue "guest-get-fsinfo" command in host.
# nc -U /tmp/helloworld2 
{"execute":"guest-get-fsinfo"}
{"return": [
{"name": "\\\\?\\Volume{5a5fadc2-c99a-11e9-b081-806e6f6e6963}\\", "total-bytes": 4843268096, "mountpoint": "D:\\", "disk": [{"bus-type": "sata", "bus": 0, "unit": 0, "pci-controller": {"bus": -1, "slot": -1, "domain": -1, "function": -1}, "dev": "\\\\?\\Volume{5a5fadc2-c99a-11e9-b081-806e6f6e6963}", "target": 0}], "used-bytes": 4843268096, "type": "UDF"},

{"name": "\\\\?\\Volume{8a5b82d7-c239-4bd1-b289-e48d8af5b9b1}\\", "mountpoint": "System Reserved", "disk": [{"bus-type": "sas", "bus": 0, "unit": 0, "pci-controller": {"bus": -1, "slot": -1, "domain": -1, "function": -1}, "dev": "\\\\.\\PhysicalDrive0", "target": 0}], "type": "NTFS"}, 
{"name": "\\\\?\\Volume{8264347c-309c-40cf-9f71-0f6ec295f807}\\", "total-bytes": 31971078144, "mountpoint": "C:\\", "disk": [{"bus-type": "sas", "bus": 0, "unit": 0, "pci-controller": {"bus": -1, "slot": -1, "domain": -1, "function": -1}, "dev": "\\\\.\\PhysicalDrive0", "target": 0}], "used-bytes": 16184545280, "type": "NTFS"}]}

Actual results:
after step2, it's "FAT32" in guest 
after step3, system reserved volume's file system is "NTFS"


Expected results:
The file system info get from guest agent is aligned with which in guest.

Comment 3 Basil Salman 2019-11-12 16:58:57 UTC 
I reproduced the issue successfully.

The issue is not only in Windows server 2019 or omvf.
i was able to reproduce it also with seabios and on other Windows releases.

I will be working on a fix for this, will send updates once i have some.
Comment 6 Basil Salman 2020-01-06 17:48:40 UTC 
I am still looking into this issue, i was able to address the issue:
as system reserved volumes do not have a mount point to windows, this causes issues for the data collection.
i am trying to implement a fix in order to still be able to collect such data on these volumes, 
if that doesn't work then i think the fix will be to disable this data collection for system reserved volumes.
Comment 8 Basil Salman 2020-04-26 17:57:49 UTC 
Hi,

Can you please confirm that the issue is fixed in this build ?

Hit this error with the new build, while works well with older version.

It works with the new build, "type": "FAT32".
