VirtualBox: boots only into UEFI Interactive Shell

1.Problem

Problem with VirtualBox 5.x running on GNU/Linux Debian 9.x host:

EFI-enabled guest suddenly boots only into UEFI Interactive Shell.

It waits for 5 seconds and then it drops to Shell&>.

I don’t remember any modifications, which I would have done, neither to the host, nor guest, or VirtualBox itself.

2.Plausible fix:

  In UEFI Interactive Shell, enter the file system:

fs0:

  Following up with creating this file:

echo '\EFI\ubuntu\grubx64.efi' &> startup.nsh

: <8195plough959595; Press CTRL+S to save the file.

: <8195arrange;: <819595; Press ENTER to confirm the file name.

: <8195019595; Press CTRL+Q to exit the editor.

: <8195containment;

reset

Important notes

  For some reason you have only a few seconds to edit and save the file. If it takes you longer, then the guest may react with a significant delay. Or it may even freeze.

  Replace debian with your system’s id, e.g. ubuntu. You may verify this by simply going into the \EFI\ directory and running ls.

Another way

  If you don’t succeed, and supposing your guest is Linux type, I myself had to do it:

  Boot from live USB with any Linux.

  Mount the root file system.

  Create this file on the mounted file system, adjust the path to wherever you have mounted it:

/boot/efi/startup.nsh

  Enter the above explained line to it.

Automatic compilation of visual build professional

Visual build Pro can help software developers automatically produce reusable projects for their software development. The software has powerful automatic compiling function, visual build Pro supports automatic creation of installation program, FTP, HTTP, LAN sharing and other file transfer modes, and has powerful log recording system and automatic running unit test cases; in addition, it also supports automatic sending mail and database operation. Visual build supports the creation of projects. Each project contains several step groups, and each group contains several steps. For example, a simple daily build can be divided into resource update, code update, automatic compilation, automatic creation of installation package, automatic running of test cases, and notification of results to relevant personnel. You can subdivide the above steps into small steps, and the subdivision is completed by visual build. Visual build defines a template for various steps. You only need to fill in different parameters according to your own project. Specific use can see the help file, the operation inside are very detailed, but some places still need to pay attention to.

GC plug in of jvasualvm + error “not supported for this JVM” + command jstatd

Plugin install

tools->plugin->Available Plugin There will be plug-ins worth installing, such as VisualGC

Plugin Lists: https://visualvm.dev.java.net/plugins.html

Note: The port configuration provided above is a bit cumbersome, so why not just do it like this.

To use VisualGC you must start the jstatd agent on the remote machine, otherwise it will show “not supported for this jvm” error.

And there is a permission problem when starting jstatd, you need to make the following changes.

[root@xxx-01 ~]# java -version

Java(TM) SE Runtime Environment (build 1.7.0_55-b13)
Java HotSpot(TM) 64-Bit Server VM (build 24.55-b03, mixed mode)
[root@xxx-01 ~]# jstatd

[root@xxx-01 jdk1.7.0_55]# jstatd -J-Djava.security.policy=/usr/java/jdk1.7.0_55/jstatd.all.policy &

Then start the jstatd command in background mode
