[Qemu-devel] [Bug 1581936] Re: Frozen Windows 7 VMs with VGA CVE-2016-3712 fix (2.6.0 and 2.5.1.1)

2016-05-15 Thread Florian Strankowski
I can confirm this behaviour. Tested on 3 different machines, all Windows 7 VMs are broke because of the latest "patch". Also tested Windows XP and Windows 10, both work with VGA flawlessly. -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to Q
