Let NetScaler CS vserver perceive lb vs's statusBy default CS vs does not perceive lb vs's State, and regardless of LB's state how CS vs is up. If you want CS vs to change with LB status, you need to enable the "State Update" feature. CS vs also becomes down when all lb of the CS vs binding is all down. This kind of demand should be more common, although netscaler in the design time Enough "self-confidence", think CS
LXC container Virtualization
After some tossing, I initially deployed LXC virtual on my work notebook. This is a very lightweight virtual solution, especially suitable for testing environments with limited hardware and a good environment for our system administrator technical training.

The following installation practices are implemented on the Gentoo x86_64
virtualization, parallel virtualization provides better performance.
Operating system virtualization
This method implements multiple independent program running environments in a system kernel, which can be understood as the implementation of chroot at a lower level. This method has the optimal performance and density, and allows the dynamic management of resources. In this way, multiple virtual hosts share the same system kernel. FreeBSD Jail, Linux
use the same kernel, in addition, all containers often share the same libc library (depending on the container configuration ). Such sharing can often be extended to other files in the directory that do not need to be written.
While providing isolation, containers also save costs by sharing these resources, which means containers are much less costly than real virtualization.
Container technology has long existed. For example, Solaris zones and BSD jails are containers on non-
and has been modified. KVM simply ignores this issue. if you want to virtualize it, you must run it on the updated hardware.
At the beginning, I thought this was inconvenient. However, considering that newer machines currently listed can support virtualization (such as Intel VT and AMD SVM), it may not take long, this will become a standard method, rather than a few exceptions.

Each partition is called a security context, in which the v

Considering that the development of virtualization technology is not long, KVM is actually a relatively new technology. Currently, multiple open-source technologies are available, such as Xen, Bochs, UML, Linux-VServer, and coLinux. However, KV
providing a method for creating and entering containers, the operating system allows applications to run as they run on independent machines, but also shares many underlying resources. For example, you can effectively share the page cache of public files (such as glibc), because all containers use the same kernel, in addition, all containers often share the same libc library (depending on the container configuration ). Such sharing can often be extended to other files in the directory that do n

In terms of virtualization, many Hypervisor (see article 1) uses the paravirt_ops interface to isolate low-level operations. due to a lot of controversy over the use of fully-virtualized Xen technology, it will be very slow to add Xen to the official kernel. KVM has be
