...grub from a "full graphic" mode to a "hires textmode",
AFAICS, this also influences all grub instances in the whole XEN
infrastructure, so it could be a influence.

PCI Passthrough not working
Further to my messages back in May I have at last got round to trying to get my DomU to recognise USB devices.
I am using Xen 4.6 with CentOS kernel 3.18.34-20.el7.x86_64.
I have to manually make the port available before creating the DomU by issuing the command:
xl pci-assignable-add 00:1a.0
otherwise nothing shows in:
xl pci-assignable-list
I have added this to my .cfg file as per the

xen4 , framebuffer and grub2
...ization error!
Could not initialize SDL - exiting
It seems that xen can not find the framebuffer device.
I have searched the web about how to enable framebuffer in grub2,someone said :
add these two lines into /etc/default/grub and run update-grub2 .(https://wiki.archlinux.org/index.php/GRUB2 )
GRUB_GFXMODE="1024x768x32"
GRUB_GFXPAYLOAD_LINUX="keep"
I have done it and reboot my server,but the problem remains.
My question is :
How to enable framebuffer in grub2?
Thank you!

[Bug 55412] New: Screen turns black during boot after driver tries to set mode on NV50
...<bskeggs at redhat.com>
An interesting thing about this bug is that it can be avoided with adding the
kernel flag nouveau.reg_debug=0x600. With this flag a wrong resolution is set
at boot and the screen does not turn black. The X Server cannot start anyway.
My native resolution is 1366x768. GRUB_GFXMODE is 1360x768x32, since the
greater resolution is not listed in grub's vbeinfo.
nouveau and blob run X with 1366x768.
I will attach a log with and without the flag at commit
97d6852410a83e413d85649cb2cc10e17d6ee2ab.
