[Xuan Luo]

hello,everyone!
I got a windows8 32bit iso,and want to try it on my VM created by Cloudstack 
4.2.0,and hypervisor is KVM.
Firstly,windows logo shows :D,then display a black backgroud with lines of 
error.Error code is 0x0000005D.I google it,somebody say KVM just cant install 
32bit win8,and 64bit will works,.Anybody tried win8 on Cloudstack 
successfully?thank you.
