Listing 6.35. Number of Loopback Devices generate, create qr code iso/iec18004 none for .net projects GTIN-13 [root@dom0]# ls /dev/ . grep loop wc -l 18 [root@dom0]#. To see wha t loopback devices you are currently using, use the losetup command as in Listing 6.36. Listing 6.

37 that the error reports that Hotplug scripts are not working. This is because the attachment of a virtual bridge causes a script to run. Listing 6.

37. Creating a Virtual Interface with a Nonexistent Network Interface Name. INCORRECT LINE IN CONFIGURATION FILE: vif = [ "bridge=xnbr0" ] ERROR GIVEN BY XM CREATE: Error: Device 0 (vif) could not be connected. Hotplug scripts not working. CORRECT LINE IN CONFIGURATION FILE: vif = [ "bridge=xenbr0" ].

In this ca VS .NET qr codes se, it was simply a typo in the name of the bridge. Listing 6.

38 shows a way to check which virtual bridges are available. In this case, there are two bridges called xenbr0 and xenbr1. Listing 6.

38. Displaying Virtual Bridges. [root@dom0 ]# brctl show bridge name bridge id xenbr0 8000.feffffffffff xenbr1 [root@dom0]# 8000.feffffffffff.

STP enabled no no interfaces peth0 vif0.0 peth1 vif3.0 However, a qrcode for .NET similar error about Hotplug scripts not working could also be thrown when /bin/sh does not point to bash. Listing 6.

39 shows the command to diagnose and fix one example of such a problem. There could be multiple reasons for this error, though, and a Web search will probably be sufficient to resolve the issue..

Listing 6.39. Fixing /bin/sh to Link to the Correct Shell Program [root@dom0 .net vs 2010 QR ]# lrwxrwxrwx 1 [root@dom0]# [root@dom0]# [root@dom0]# lrwxrwxrwx 1 [root@dom0]# ls -l /bin/sh root root 4 Dec 6 19:08 /bin/sh -> dash rm -f /bin/sh ln -s /bin/sh /bin/bash ls -l /bin/sh root root 4 Dec 6 19:08 /bin/sh -> bash. Problem 7: Running the Wrong Kernel in Domain0 Some error Visual Studio .NET Denso QR Bar Code s occur that aren"t specific to xm functionality. One example is when xm fails to run because you"ve booted a non-Xen kernel in Domain0.

You can check that you are using your Xen kernel by running one of the two following commands shown in Listing 6.40. Listing 6.

40. Ensuring That a Xen Kernel Is Running in Domain0. [root@dom0 ]# uname -r 2.6.16.

29-xen [root@dom0]# cat /proc/xen/capabilities control_d [root@dom0]#. The uname qr codes for .NET command displays the version of your kernel (not necessarily 2.6.

16.29). However, Xen-enabled kernels typically have "xen" appended to the end of the version number when they are compiled.

If this is not the case, you can also check whether /proc/xen/capabilities exists. This file should only exist when a Xen kernel is booted. If you are not running the Xen kernel, fix the Domain0 kernel line of your GRUB entry to use the Xen kernel.

For instructions on how to do this, see 4, "Hardware Requirements and Installation of Xen Domain0." Of course, another sign that you are running a non-Xen enabled Domain0 kernel is when an error appears when you start the xend daemon. If you encounter such a message, as in Listing 6.

41, you are more than likely not running a Xen enabled kernel in Domain0. You may not even be running the Xen hypervisor. So double-check your GRUB menu file to see whether you started your system with the Xen kernel.

Listing 6.41. Attempting to Start the Xen Daemon When in a Non-Xen Kernel.

[root@dom0 ]# /etc/init.d/xend start grep: /proc/xen/capabilities: No such file or directory [root@dom0]#. Problem 8: Loading a Kernel Without Modules Another co mmon set of problems can arise when loading guest kernels that build Xen drivers and other needed drivers as modules instead of directly in the kernel. If you receive errors when booting a guest, double-check whether you are using any modules by searching for .ko files in the /lib/modules/<kernel-version> directory that correlates to the guest kernel version on Domain0.

If you find any .ko files, you are using loadable modules, and it"s likely you need an initial RAM disk (initrd) image to let the kernel know what modules are available during the boot sequence. You must assign the location of your initrd image to the ramdisk variable.

Also, make sure your guest image contains the proper /lib/modules directory. For instructions on how to add the /lib/modules directory to your guest image, see 5. A good way to diagnose this type of problem is.
