Yes, rebooting worked.  I was able to exercise xl commands.
 
The next time I rebooted, the system errored.
 
The boot process progressed through a report
    Dom0 has a maximum of 4 CPUs
 
The next screen was a warning
    Failed to connect to lvmstad.  Falling back to device scanning
 
The next tow lines address /dev/mapper/mymachine-root:
    recovering journal
    clean, 399/1525920 files, 398509/6103048 blocks
 
The next 5 lines was a sequence of errors on attempting to load wireless drivers:
[    10.722951 iwlwifi 0000:02:00.0: firmware:  failed to load iwlwifi-7265D-26.ucode (-2)
[    10.7xxxxx iwlwifi 0000:02:00.0: firmware:  failed to load iwlwifi-7265D-25.ucode (-2)
[    10.7xxxxx iwlwifi 0000:02:00.0: firmware:  failed to load iwlwifi-7265D-24.ucode (-2)

[    10.7xxxxx iwlwifi 0000:02:00.0: firmware:  failed to load iwlwifi-7265D-22.ucode (-2)
 
(I do not know if this is relevant, but I just got wireless working on the laptop so I could install xen-tools.  I was able to get wireless to work through configuration of /etc/networks/interface.)
 
iwlwifi are Intel dual band wireless AC 7265 device drivers for different versions of the hardware.  I installed drivers when the system was originally built.  I only loaded the latest which was 7265D-25.  I just found 7265D-26 on Intel's website but I have no idea how to load it without a complete boot.
 
How should I progress?

Re: Stretch Boot Failure

Xen boot fails per the below description. 
 
I have booted into Debian (dom0) with no problem. 
 
I updated then upgraded from dom0, it booted once OK.  The second time it failed.
Should I have updated then upgraded Debian first? 
 
What would be a good recovery process?
 
BTW,  wireless doesn't work when I boot into Debian.  I had just gotten wireless to work in dom0.

Stretch Boot Failure, 2

ray-2
[Re-written for clarity]
 
Xen boot fails. During boot, there is a note on missing wireless driver and than on a video error. The video error is repeated continuously and I can only stop it by turning the laptop off.
 
I can boot into Debian at the boot selection.  There is a  boot error for the wireless but boot completes.  But wireless does not work.
 
History:
Debian 9 was loaded onto the machine. 
Wireless drivers were loading during system installation.  The driver versions installed (as noted as missing on previous installation attempt), were:
iwlwifi-7265D-12.ucode
iwlwifi-7265D-13.ucode
iwlwifi-7265D-14.ucode
iwlwifi-7265D-15.ucode
iwlwifi-7265D-16.ucode
Wireless worked. 
 
Ran apt-get update.
Ran apt-get upgrade.
Xen 4.8.1 was loaded with ap-get.
 
Rebooted into Xen.  Wireless did not work.
Eventually got wireless working (only configuring /etc/network/interfaces).
Ran apt-get update.
Ran apt-get upgrade
Loaded xen-tools with apt-get
 
Rebooted OK.
Xen-tools worked.
 
Attempted reboot again but received error on loading wireless and display.
Wireless error:
[    10.722951 iwlwifi 0000:02:00.0: firmware:  failed to load iwlwifi-7265D-26.ucode (-2)
[    10.7xxxxx iwlwifi 0000:02:00.0: firmware:  failed to load iwlwifi-7265D-25.ucode (-2)
[    10.7xxxxx iwlwifi 0000:02:00.0: firmware:  failed to load iwlwifi-7265D-24.ucode (-2)
[    10.7xxxxx iwlwifi 0000:02:00.0: firmware:  failed to load iwlwifi-7265D-23.ucode (-2)
[    10.7xxxxx iwlwifi 0000:02:00.0: firmware:  failed to load iwlwifi-7265D-22.ucode (-2)
 
 Display error:
...[drm.gen8-irq_handler [i915]]  *Error fault  error on pipe A0x00000100
 
Since Debian boots with the wireless error, I am guessing that xen also should continue its boot.  So it seems the problem may be in the display error.  But googling the error, I have not found where this display error is fatal. 
 
Any suggestions on how to resolve this?
 
Just for reference, I found some related but not exact issues.  But I don't see a solution.
 
Maybe I should remove xen and reinstall.
 
Thanks,
Ray
