DingDing Error: missing mainframe dll [How to Solve]

Repair steps:
1. Press “windows logo key + X”, Start Windows PowerShell (administrator) Enter the command “auto repair system
2. Dism/online/cleanup image/scanhealth” to scan all system files and compare them with the official system files to scan for inconsistencies in the computer
3. The command dism/online/cleanup image/checkhealth must be used when the system file is found to be damaged after the previous command is executed
4. Dism/online/cleanup image/restorehealth this command restores those different system files into official system source files
5. Restart after completion. No matter whether the above is successful or not, type the following command: SFC/scannow

Linux boot prompt “failed to initialize Hal!” solution

My operating system is debian5. There are some directories under/etc/that are RC *. D. * stands for numbers, which are all the services loaded when the system starts. Find DBUS and Hal in them. Pay attention to the numbers in front, which represent the startup order. For example, I found k88dbus and k16hal in RC1. D directory. The problem is that the startup order of DBUS is behind Hal, So it causes this problem. Therefore, write the startup sequence of dubs between Hal serial numbers. For example, I change k88dbus to k15dbus, and use the following command:

#mv K88dbus K15dbus

Restart again and the problem is solved.

Building virtual machine environment based on kvm-qemu under ubuntu12.10 (12)

In addition to the initial mounting of the optical drive in the definition file of the virtual machine, Libvirt also has a dynamic platter mount method, which USES the Attach -device command in the virsh command. The format of this command is as follows:

dev@devhost:/opt/vm/xpvm1$sudo virsh attach-device < domain-name> filename

Where filename is a file defined in XML format (we’ll call it Disk.xml) :

< Disk type = “file” device = “cdrom” & gt; < The source file = “/ opt/vm/drivers. Iso/& gt;” < Target HDC dev = “”/& gt; < readonly/> < /disk>

The virtual machine was originally mounted ona CD-ROM called Windows_xp_professional_sp3_x89.ISO:

< domain type=’kvm’> & lt; name> XP_VM< /name> & lt; uuid> 91f15b08-e115-4016-a522-b550ff593af9< /uuid> & lt; memory> 1024000< /memory> & lt; currentMemory> 1024000< /currentMemory> & lt; vcpu> 1< /vcpu> & lt; os> & lt; Type the arch = ‘x86_64 machine =’ PC ‘& gt; hvm< /type> & lt; boot dev=’hd’/> & lt; boot dev=’cdrom’/> & lt; Bootmenu enable = ‘yes’/& gt; & lt; /os> & lt; features> & lt; acpi/> & lt; apic/> & lt; pae/> & lt; /features> & lt; cpu> & lt; The topology sockets = ‘1’ cores = ‘1’ threads = ‘1’/& gt; & lt; /cpu> & lt; = ‘localtime’ clock offset/& gt; & lt; on_poweroff> destroy< /on_poweroff> & lt; on_reboot> restart< /on_reboot> & lt; on_crash> restart< /on_crash> & lt; devices> & lt; emulator> /usr/bin/qemu-system-x86_64< /emulator> & lt; = ‘disk disk type =’ file ‘device’ & gt; & lt; Qemu driver name = ‘ ‘type =’ qcow2 ‘/ & gt; & lt; The source file = ‘/ opt/vm/xpvm1 xp_c.

After installing the system, what you see in the virtual machine is:

 
Instead of re-closing and defining a new disc file, we can change the disc using the Virsh Attach – Device command:
 

dev@devhost:/opt/vm/xpvm1$sudo virsh attaching -device XP_VM disk.xml

 

The advantage of doing this is that in some cases we can achieve the effect of a hot plug disc without having to restart the virtual machine.
Note: It should be noted that, after testing, there must first be an initial optical device in the defined XML, otherwise the execution of another optical device will fail: internal Error No device with bus ‘ide’ and target ‘HDC’ reported error.
That is, this is actually a swap, not a dynamic mount, and the cd-ROM device itself must be defined in XML before the virtual machine can be started.

Unable to set resolver from resolv.conf; startup
Check out my resolv.conf and find:

guoyanzhang@bogon:/etc/network$ cat /etc/resolv.conf 
# Generated by NetworkManager
nameserver fe80::1%wlp8s0
nameserver 192.168.1.1

The first nameserver looks like a nameserver and has been modified as follows:

guoyanzhang@bogon:/etc/network$ cat /etc/resolv.conf 
# Generated by NetworkManager
nameserver 8.8.8.8
nameserver 8.8.4.4

The reason is that this file was not configured in debian system at the beginning. This file was generated after I successfully installed it on the Internet. Now delete ISC-DHCP-Server and install it like this:

Using apt mirror to build Debian local warehouse

transfer: https://www.cnblogs.com/keithtt/p/7410874.html

apt-mirror is able to download the official image locally and keep the directory structure consistent with it, but it is not possible to modify the mirror repository. If you want to modify the mirrored warehouse, you need to use Reprepro.

1. Apt-mirror 

# aptitude update
# aptitude install -y apt-mirror

# dpkg -L apt-mirror
/.
/usr
/usr/bin
/usr/bin/apt-mirror
/usr/share
/usr/share/man
/usr/share/man/man1
/usr/share/man/man1/apt-mirror.1.gz
/usr/share/doc
/usr/share/doc/apt-mirror
/usr/share/doc/apt-mirror/changelog.gz
/usr/share/doc/apt-mirror/changelog.Debian.gz
/usr/share/doc/apt-mirror/copyright

/etc/cron.d

/etc/apt
/etc/apt/mirror.list
/var
/var/spool
/var/spool/apt-mirror
/var/spool/apt-mirror/skel
/var/spool/apt-mirror/mirror
/var/spool/apt-mirror/var

2, modify the configuration file and add the source to download (I have added the source for debian_squeeze here) 

# vim /etc/apt/mirror.list

set base_path    /docker/debian_mirror
set mirror_path  $base_path/mirror
set skel_path    $base_path/skel
set var_path     $base_path/var
set cleanscript $var_path/clean.sh
set defaultarch  <running host architecture>
set postmirror_script $var_path/postmirror.sh
set run_postmirror 0
set nthreads     40
set _tilde 0

deb-amd64 http://archive.debian.org/debian squeeze main
deb-amd64 http://archive.debian.org/debian squeeze-lts main

3. Manually run apt-mirror to download the mirror

0 bytes in 0 files and 0 directories can be freed.
Run /docker/debian_mirror/var/clean.sh for this purpose.

4. Set the timing task to synchronize the timing with the official source 

# vim /etc/cron.d/apt-mirror
0 0 * * * apt-mirror > /docker/mirror.log 2>&1

5, set publishing directory soft link 

# ln -sv /docker/debian_mirror/mirror/archive.debian.org /docker/mirror

6, configure nginx publish mirror directory 

# cd /usr/local/nginx/conf/vhosts/
# vim debian_mirror.conf

server {
    listen 8081;
    server_name debian_mirror;

    root /docker/mirror
    location/{
        autoindex on;
    }

    access_log /usr/local/nginx/logs/debian_mirror.access.log oupeng_logs;
    error_log /usr/local/nginx/logs/debian_mirror.error.log;
}

# /usr/local/nginx/sbin/nginx -t
# /usr/local/nginx/sbin/nginx -s reload

7, find a debian6 machine to add local source test 

# vim /etc/apt/sources.list
