Discuss the 5.2.8 release here.
You can download the release here.
Mainly a regression-fix release for 5.2.6.

On Ubuntu 18.04 the package libcurl is update to version 4 but virtualbox require libcurl3, it's time to open a new repo.

Upgrade path 5.1.30 -> 5.2.8, all VMs powered off. After installing GA 5.2.8, mouse integration is no longer available in Windows 10 and Windows Server 2016 guests Host: Windows 7 x64

EDIT: To fix it, you have to shutdown the VM after the GA installation (after guest reboot it is broken) and start it again.

It still is 18.03 (today actually, Happy new month). So I'd wait for the next revision. This is not a new 5.2.8 issue or a regression, is it?

You didn't reboot your guest? And what does "reboot is broken" mean?

I did following steps (note the issue was not present in Windows Server 2008 R2 VM)

1. Start VM (Windows 10 or Windows Server 2016, powered off state)
2. Login to Windows, old GA 5.1.30 installed (mouse integration works)
3. Start GA 5.2.8 installer, it finishes, asks to reboot (mouse integration is already broken at this stage)
4. Reboot
5. Login to Windows, GA 5.2.8 is installed (mouse integration is broken)

Now you can repeat steps 4 to 5 many times, mouse integration is still broken, disabled in Input VM window menu.

To fix it you have to:

6. Shutdown the guest OS (to finish the VM session)
7. Start it again

It looks like something was broken in the VM session after GA update.

Ubuntu 18.04 (Codename Bionic Beaver) is next release and released on April 26 2018 and is an LTS, actually is still in development and actually i'm using for testing with installing virtualbox and other program, at this time libcurl is upgraded to version 4 but at this time it's not possible to upgrade this library and relative dependencies

@trekfan1
In case you missed my first reply, 18.04 is not yet released. It is not supported... yet.
And again. This is *not* a 5.2.8 new issue...

Can you explain that part a little bit better? Because most of my VMs are "frozen" with the 5.1.26 GAs, and I've never, ever seen a behavior like the one you're trying to describe here. Is your pointing device set to "USB Tablet"? Anything else that might be out of the ordinary?

First and foremost: is this something that you see with 5.2.8 only? Or was it happening before that? Because if this is *not* a new behavior with 5.2.8, open a new thread. Otherwise, can you provide a VBox.log from a complete start/login/shutdown the VM process? ZIPPED!

I have lately noticed high CPU usage (100 % percent) in the host OS (Arch Linux) when guest OS (Arch Linux) have a Chromium/Google Chrome web browser running with several tabs open, in which each have quite heavy usage of javascript. Mostly the browser is idling in the background and guest CPU usage is low (below 10%).

This happens at current release and in previous test builds of 5.2 series.

I would like to thank all VB developers for their great job!

Sometimes I have the impression the forum lacks a bit of appreciation.

The new VB release 5.2.8 "feels" much more quicker than any other previous release.
I have no concrete numbers but all machines are much faster than before.

Keep up the good work and have a nice week-end!

It's because they didn't include all the Spectre/Meltdown fixes! Yet!
(Just kidding, I don't really know what they have included or not)

But, if you want to see some slowdown (disclaimer: I haven't tried it yet), try the 5.2.8, newly added:

• VBoxManage modifyvm <name|uuid> --spec-ctrl on|off

What it actually does, is left as an exercise...

No, the pointing device is set to: PS/2 Mouse

As I wrote, it happened after VirtualBox update from 5.1.30 to 5.2.8 version and I haven't seen it before either. Fortunately I have few old Windows 10 5.1.30 VMs I haven't started yet so I can reproduce the issue again. Logs and screenshots attached.

Yes, I can confirm that.

Why? The default in the template calls for a USB Tablet. Why did you change it to PS/2? Please revert it to the default. Windows 10 will never see more than 1% of PS/2 mice in real life

socratis wrote:Why? The default in the template calls for a USB Tablet. Why did you change it to PS/2?

I don't know, I guess it is the default value. Note that I don't install USB support because I don't need it and there were issues with the driver.

When I change it to "USB Tablet", it displays the exclamation mark icon, probably because of the missing USB support (USB Controller is disabled). Anyway, I already did many VB upgrades having this mouse setting and I have never had such issue before. Fortunately there is simple fix.
