Created attachment 1474763 [details] Engine log Description of problem: On Windows 10 or Windows 2016 guests (64 bit), when creating a snapshot the user receives the warning, although the guest tools are installed and guest agent is running: Could not detect Guest Agent on the VM. Note that without a Guest Agent the data on the created snapshot may be inconsistent. Version-Release number of selected component (if applicable): ovirt: 4.2.4.5-1.el7 Guest tools: oVirt Guest Tools 4.1-5.fc24, or 4.2-1. The following services are running within Windows guest: - Ovirt Guest service - Qemu guest agent - Qemu Guest Agent VSS provider The engine dashboard shows also that the guest agent is ok since guest apps are listed, IP details are shown and no complaint about missing guest agents under Virtual Machines listing. How reproducible: always Steps to Reproduce: 1. Click at Create snapshot 2. The warning is received 3. Actual results: The snapshot is taken. There are cases where the VM is rendered unresponsive, though this might not be related with this issue. Expected results: since the guest tools are successfully installed, the user should not receive such warning. Additional info: Attaching vdsm.log and engine.log since start of VM until snapshot of VM.

can you please add the database entry for that particular VM from engine's db? su - postgres psql engine select app_list from vms where vm_name = 'NAME';
either way, this was broken 5 years ago by wrong AgentAppName introduced in c6eaf6e17ae1002df4dbcd03acbf1bf5a099a939 The list is incorrect for upstream as it is missing the "RHEV-Agent" name still in use on Windows. Adding Lev to consider changing that, though it may not be worth it really as it would be problematic for older setups. RHV should work fine since it uses a different list Also, we should really be looking for qemu-ga ("QEMU guest agent" in Windows, not reported yet in Linux(missing in applications_list in ovirt-guest-agent.conf). Tomas, would you please open a followup bugs for fixing that since we will need that for ovirt-ga "elimination"

Michal, Femi reported failure on linux guests as well, not windows only. Can you please cross check?
Michal, assuming line to be changed is: select fn_db_update_config_value('AgentAppName','ovirt-guest-agent-common,ovirt-guest-agent','general'); what should be the value to be added? "OVirtGuestService"? "OVirt Guest Service" ?
(In reply to Michal Skrivanek from comment #3) > The list is incorrect for upstream as it is missing the "RHEV-Agent" name RHEV-Agent is not used in oVirt guest service as far as I can tell.

I only looked at VMs in setups around me. There were quite a few VMs but it is entirely possible there was no ovirt-guest-tools but rather the RHV tools everwhere. > Michal, assuming line to be changed is: > select fn_db_update_config_value('AgentAppName','ovirt-guest-agent-common,ovirt-guest-agent','general'); > what should be the value to be added? "OVirtGuestService"? "OVirt Guest Service" ? The Windows service name is not part of the guest agent code. I don't know where and how it is set. But yeah, but the bug description should be enough - "Ovirt Guest service" You could change it to match one of the existing values (they're really just one, since it's a string match the ovirt-guest-agent-common is redundant) if you want. > Michal, Femi reported failure on linux guests as well, not windows only. > Can you please cross check? please add that to this bug, I do not have any additional information and the bug doesn't have any details whatsoever. AFAIK on linux it should work just fine, unless someone would use the ancient "rhev" or "rhevm" named versions on el6.
the "Qemu Guest Agent VSS provider" is what's really interesting. So for snapshots that's the one which should be checked on Windows. But we need the name to match the AgentAppName list for other (slightly obscure) things too (SSO, RDP, TZ check)

I am wondering if there is any progress on this. In case I will gladly do so.
we really just need bug 1615830

Since raw disks are not supported, a user needs to create a snapshot including the disks to enabled incremental backup for the disks. you can visit https://www.adobesupportphonenumber.com/blog/fix-photoshop-scratch-disk-full-errors/ to fix out this issues.
oVirt Guest Agent is going away, but leaving this until the parent is on MODIFIED and testable
Re-targeting to 4.3.1 since it is missing a patch, an acked blocker flag, or both
Hi all, We're experiencing the same issue on the following configurations: Windows 2012R2 x64 - oVirt 4.3.5.5-1.el7 Windows 2019 x64 - oVirt 4.3.3.2-1.el7 I've confirmed that the QEmu / oVirt Guest agent services are installed and running on both. It looks like this bug has been closed, but I can't tell when/if it has been fixed. Is a fix planned for a future release? It's also not clear from this discussion if the warning is okay to ignore, or not. Thanks in advance. Jeremy
