Hi,
This issue only happens on my IA32E VMX domain. IA32 VMX domain is okay.
I am trying VBD disk in IA32E VMX domain. I used following disk configuration to create an IA32E VMX domain.
disk = [ 'file:/mnt/disk1.img,hda,w', 'file:/mnt/disk2.img,hde,w' ]
After creating VMX, its keyboard can not be used properly. For example, if pressing 'Backspace', it shows 'm'; if pressing 'Enter', it just said Unknown key pressed.
If I didn't set 'hde', or just change 'hde' to 'hdd', everything is okay. Could anyone help to reproduce and explain this strange issue?
Best Regards,
Yongkang (Kangkang) 永康

What OS are you running as the particular HVM guest?

I don't think hde is a valid disk drive for HVM. QEMU only emulates a
standard IDE controller which would only allow 4 disks (hda, hdb, hdc,
hdd). AFAIK, Xen has not added an additional IDE controller.
Sounds like we're not doing appropriate error checking somewhere...

Sorry 'bout the noise. Still catching up. Didn't realize hde could be
used for paravirt devices.

Hi,
I have tried that patch. It fixes the issue in 32E VMX. With it, keyboard is normal when I use "hde+" disk configuration for VMX. And after insmod VBD modules, that hde disk can work. Will that patch go into xen-unstable? :)
A little puzzled why it only influent 32E VMX.
Also thanks to Anthony, the 'xvda' more likes a clear way to use VBD in VMX. :)
Best Regards,
Yongkang (Kangkang) 永康
