Generally, virtual machine image files are directly stored in an IMG image file or directly partitioned using/dev/SDA. However, if the Virtual Machine partition is "broken", it will be hard to recover.
Qemu supports qcow2, an image format that allows you to create Incremental Images. This allows you to store modifications in new files and protect the original image when an error occurs. This function is very useful,[Xen seems to support qcow2, to be

Background:The SMS function is provided to the customer's Development System. The device used is the jindi serial port SMS cat. After the system is developed and released to the customer, it finds that the SMS cannot be sent out.
Cause:The system used during development is centos4, while the system installed for the customer is centos5. The default installation for centos5 is with the
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 the xen

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 host memory plus
