Green Dragon Posted November 10, 2022 Share Posted November 10, 2022 Hiya! I'm configuring vm backups using the vm backup plugin and I want to enable snapshots. When I do I find the following recommendation: "IMPORTANT: It is highly recommended that you install the qemu guest agent on your VMs before using snapshots to ensure the integrity of your backups." As Im unfamiliar with vm backups I have no idea what this is suggesting. I looked in the configuration for the vm and see nothing related to qemu and the only installable community app i find is qemubackup which does not clearly indicate that its what I'm looking for. Any assistance, education, or clarification would be greatly appreciated! Quote Link to comment

Aaaah, Thanks! So, for a windows server 2003 vm I need to install a qemu client from within the vm desktop? Quote Link to comment

Go to the mounted ISO in explorer The guest agent installer is in the directory guest-agent Execute the installer with double click (either qemu-ga-x86_64.msi (64-bit) or qemu-ga-i386.msi (32-bit) Edited November 10, 2022 by SimonF Quote Link to comment

Im getting a fatal error trying to install the msi. 'A program run as part of the setup did not finish as expected'... <sigh>... Quote Link to comment

Windows Screen-vioserial-device-manager.png Screen-vioserial-driver.png First you have to download the virtio-win driver iso (see Windows VirtIO Drivers). Then install the virtio-serial driver: Attach the ISO to your windows VM (virtio-*.iso) Go to the windows Device Manager Look for "PCI Simple Communications Controller" Right Click -> Update Driver and select on the mounted iso in DRIVE:\vioserial\<OSVERSION>\ where <OSVERSION> is your Windows Version (e.g. 2k12R2 for Windows 2012 R2) Quote Link to comment

It should be noted that I changed the default COM port to 12. This vm hosts a bulletin board system (bbs) so the default COM port is remapped in order that the netserial adapter (IP to COM) can operate over COM ports 3 and 4. I'll disable the driver, reset the COM port and see if this works. Quote Link to comment
Green Dragon Posted November 11, 2022 Author Share Posted November 11, 2022 Well, I disabled my serial adapter, reset the default windows COM port to 1 and tried to install the qemu guest agent. Same error, 'A program run as part of the setup did not finish as expected'... Realized I didn't have SP2 installed so I did that. No joy... Still getting the error. Quote Link to comment
Stan464 Posted November 22, 2022 Share Posted November 22, 2022 You may need to try an Older version of the QEMU Guest Tools / Installers. 2003 is getting very very old and good portion of things do not support it anymore. Quote Link to comment

Seems reasonable. Believe me when I say that I wish this software would run on a newer OS. Where can I find older versions of the tools? Quote Link to comment
