Use the character tool xm to manage xen save, stop, and pause. Objective: To conveniently manage xen virtual machines by running the xm command. Command list: xm list: list of all known virtual machines xm create: Start an unmanaged Virtual Machine xm top: Provide an overvie
Vcpu-list [domain-id]Lists vcpu information for a specific domain. If no domain isSpecified, vcpu information for all domains will be provided.
Vcpu-pin domain-ID vcpu CPUsPins the vcpu to only run on the specific CPUs. The keywordAll can be used to apply the CPUs list to all vcpus in the domain.
Normally vcpus can float between available CPUs whenever xen deemsA different run state is appropriate. Pinning can be usedRestrict this, by ensuring certain vcpus can only run on certainPhysical CPUs.
Display memory inconsistency between XM list and XL list
This problem occurs on a Windows VM on xen4.1.2:# XM list test6Name ID mem vcpus state time (s)Test6 16 512 2-B ---- 158.0# XL list test6Name ID mem vcpus state time (s)Test6 16 2048 2-B ---- 158.6
Two different tools are used to view the same Vm, and the memory size is nearly 2 GB.
Because the implementation mechanisms of

However, it integrates the iris pro5200 series with unprecedented performance, the performance of this core display can be directly comparable to that of the mid-range independent graphics card.

Some sections in XML are always repeated, I have Ed these file by WCF.
I thought it's caused by buffersize of WCF or flush method of stream. (I don't what meaning of flush method is)
It took me about an half day to find cause of this probelm. And now, I find it's because I close stream in another thread.
Why close stream in another stream?
I intended to visit property of stream in another thread, but system throw exption somtimes because the stream was closed. So I closed stream after visite

The strange thing is to connect to the Guest console according to the official RHEL file, but the system is like a dead fish, no response !! Check the/var/log/message of Guest and find that there is no console. After one afternoon, it seems that the security permission cannot allow the console to log on !! However, this should be because the console of the root user should not respond to the Guest. Check whether the Guest still needs to be set. Otherwise, the command
Meanings of several States in XM list
Run the xm list Command. In the result, the state segment can list the status of the xen domain in step 6, and the State is one of the following.R-runDomain is running in CPU
B-blocking domain blocking means that this domain is not in the running or runnable state. This may be because the domain is waiting for Io (a traditional wait state) or is already in sleep st
There are three reasons for doing this:
1) I have modified the Linux kernel, but it cannot be started normally. I cannot enter the system and cannot use dmesg. Therefore, I want to use the serial port debugging function to output the startup information.
2) I checked a bunch of information on the Internet and tried to output xen hvm via serial port. I tried minicom and gtkterm on the client, but it was not successful...
3) In xencommonproblems, you can use the
I bought the sbc8530 single-board machine of timll for development. The manual page says it is compatible with the beagleboard-XM interface. It is made according to the pictures of others. You can use it as needed. However, it is also a luxury to use it. network interfaces are not available. After you enter the system and run ifconfig, there is only one Lo, and no Nic can be found. The attempt to load the kernel through NFS and TFTP also fails. In U-b
