Comment 3 Katerina Koukiou 2021-01-22 12:38:04 UTC

Yunming can you please try to reproduce this bug with a newer version of cockpit-machines?

I just tried with 236 and microsoft-edge-dev-89.0.767.0-1.x86_64.rpm which I downloaded from https://www.microsoftedgeinsider.com/en-us/.

With this combination of newer edge and newer cockpit-machines I can't reproduce this.

Comment 4 YunmingYang 2021-01-25 07:02:41 UTC

Of course, I try it with cockpit-machines-236-1 and microsoft-edge-88.0.705.50(Official building) in a windows VM, and the issue is disappear with the combination.

This was most likely fixed by:

    machines: Replace DesktopViewer with upstream component from PF4

Comment 6 Katerina Koukiou 2021-01-27 10:47:29 UTC

Note: For the older versions of Edge, which are not based on Chromium this is still an issue. We don't plan to investigate further or fix this bug for the non-chromium based Edge.

Comment 10 YunmingYang 2021-02-07 03:11:09 UTC

Test Versions:
cockpit-machines-237-1.el8.noarch
cockpit-236-1.el8.x86_64
libvirt-dbus-1.3.0-2.module+el8.3.0+6423+e4cb6418.x86_64


Test Steps:
1. Open cockpit-machines with Edge (which is based on chromium)
2. Click 'Launch Remote Viewer' button of a running VM

Test Results:
There is a file downloaded after clicking 'Launch Remote Viewer' button

According to the results, move the status to VERIFIED.
