The server hard disk has been upgraded and the memory is still waiting. The memory is ordered with the hard disk. I don't know why it hasn't arrived yet. I finally found out why the RAID0 test result was abnormal the day before yesterday, A hard disk is faulty ~ There is a problem with the newly purchased unpacked hard disk. Currently, most SUN servers only have 2 GB-8 GB of memory. After the upgrade, the memory size should be 8 GB-32 GB, so that more memory can be allocated to each

CentOS 5.X Installation configuration Xen virtual machine and basic usage 1. Prerequisite Requirement 1.1. IntroductionXen is free software released under the GNU GPL and is designed to provide a system environment that is highly efficient, capable of supporting the simultaneous operation of different operating systems and independent of each operating system, and Xen is a virtual machine controller devel

This article on the VPS used several common technology OpenVZ, Xen, KVM to do a simple introduction and comparison, in case you choose your own appropriate VPS Many people see the same configuration of the VPS price difference is very large, it is not understood, in fact, there are many types of virtual VPS use, such as OpenVZ, Xen, KVM, Xen and HVM and PV.

Since 0.1.0Boot The Dev attribute takes one of the values "FD", "HD", "CDROM" or "network" and is used to specify the next boot device to consider. the boot element can be repeated multiple times to setup a priority list of boot devices to try in turn. the boot element cannot be used if per-device boot elements are used (see disks, network interfaces, and USB and PCI devices sections below ). since 0.1.3, per-

Since the RHEL6 version, Redhat is not the original support Xen, instead of the embrace of KVM. Although KVM claims to support the full virtualization of HVM technology, KVM started late after all, far less mature than Xen technology, the system crashes often occur when running multiple instances, and certainly does not exclude the possibility that future KVM will be more efficient. So there are only two wa

Xen virtual machines by default do not allow different virtual machines to use different system time, so the system time of all virtual machines will be strictly synchronized with the system time of the host machine, when you use the date command to modify the VM system time, the system time remains unchanged even though the prompt is successful. If you have special requirements for independently modifying

Many servers in the data center perform xen virtualization. Suddenly, the memory size detected by free-M differs greatly from the actual memory size of the server .. I found a lot of information and compared several virtualized servers to find the kernel problems after virtualization. * ***** If the actual memory of the server is less than or equal to 32 GB, after xen virtualization, the

The key to migrating a VM from KVM to Xen is to replace the original kernel without Xen patches, and then select the appropriate grub (older versions of Xen do not support grub2 ). After completing the preceding two steps, make the image of the KVM virtual machine into an Xen image, and then use the configuration file
