Description Juan Orti 2021-11-25 15:39:59 UTC 
Description of problem:
In bug 1898985 the documentation for upgrading the virtio-win drivers was updated to recommend using Windows update or using "netsh dump" to save the network configuration and then restore it.

This is risky or not feasible for several reasons:

- Windows update only works for Windows 2019. Older versions like 2016 are not getting the drivers.
- netsh dump poses some risk for VMs with multiple NICs for iSCSI, Windows clustering, backup etc.
- Dump transfer via netsh is not identical (this is problem of the netsh utility).
- netsh method is a potencial risky operation when you have to update hundreds of production VMs.

Version-Release number of selected component (if applicable):
virtio-win-1.9.19-1.el8.noarch

How reproducible:
Always

Steps to Reproduce:
1. Have Windows VM with static IP and an old version of virtio-win.
2. Run the installer virtio-win-guest-tools.exe

Actual results:
IP configuration is lost.

Expected results:
IP configuration preserved and drivers and qemu-ga updated.

Additional info:
We have seen that if you first update the NIC drivers and then run the installer, the IP configuration is preserved.

So the proposal for this bug is to modify the installer so it performs these steps in order:

1. Update NIC driver.
2. Remove old versions of the agent.
3. Upgrade everything else.

Hi Vadim,

I found two related bugs.The current solution is to warn users when they want to remove or upgrade the driver.
But currently bz2005220 has not been fixed.So we can not recive any warning now.
So is this bug a duplicate of 2005220?

Well, technically the problem with warning the user needed to be split
into two different parts :
- .msi (https://bugzilla.redhat.com/show_bug.cgi?id=1965552) - FIXED
- and the bundler (.exe) https://bugzilla.redhat.com/show_bug.cgi?id=2005220 - this problem is a way more complicated than .msi and is not fixed yet.

All the best,
Vadim.

Hi Peixiu,
It is an installer related issue. I'm going to start working on it 
after virtio-win drivers code freeze. 

Best,
Vadim.

Comment 29 Vadim Rozenfeld 2023-08-21 06:21:23 UTC 
the static ip backup/restoring functionally has been implemented. If other settings like DHCP, DNS, WINS or even storage related settings need to be preserved and restored during the virtio-win drivers update, then please open a new bug/jira issue with the exact list of parameters.

Best,
Vadim.

Hi Germano and Juan,

We suppose that keeping IP configurations would be sufficient to fix this bz, would you please help check the above comment 29 and confirm if there is other requirement from customer side? Thanks.
