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-23.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?
