此文放在evernote快发霉了,整理一下放出来。

  1. virsh start vm1368544020451  

 error: Failed to start domain vm1368544020451

error: internal error process exited while connecting to monitor: kvm: -drive file=/dev/sp1368155439693/v1368544020461,if=none,id=drive-virtio-disk0,format=qcow2: could not open disk image /dev/sp1368155439693/v1368544020461: Invalid argument

 

镜像格式错误,用qemu-img info 检查镜像和xml配置文件中指定的type是否一致。

 启动虚拟机错误:

lzjun@lzjun-ubuntu:/opt/vm$ sudo virsh start vm0

error: Failed to start domain vm0
error: internal error process exited while connecting to monitor: Could not access KVM kernel module: No such file or directory
failed to initialize KVM: No such file or directory
No accelerator found!

 

上面的提示信息就是因为QEMU在初始化阶段因为无法找到kvm内核模块。

sudo modprobe kvm   #载入指定的模块

重启电脑,进入bios界面,设置advance选项里面的virtualization标签为Enabled

通过命令 lsmod | grep kvm    #显示已载入的模块

 虚拟机迁移:

# virsh migrate --live 1 qemu+tcp://192.168.0.121 --p2p --tunnelled --unsafe 

error: operation failed: Failed to connect to remote libvirt URI qemu+tcp://192.168.0.121(在URI后面加上/system,‘system’相当于root用户的访问权限)

#virsh migrate --live 2 qemu+tcp://192.168.0.121/system --p2p --tunnelled

 error: Unsafe migration: Migration may lead to data corruption if disks use cache != none(加上--unsafe参数)

#virsh migrate --live 2 qemu+tcp://192.168.0.121/system --p2p --tunnelled --unsafe 

error: Timed out during operation: cannot acquire state change lock (启动虚拟机有时也会遇此错误),需要重启libvirtd进程

 #virsh

error: Failed to connect socket to '/var/run/libvirt/libvirt-sock': Connection refused(libvirtd 进程没有启动,libvirtd是一个监听客户端请求的进程)

$ virsh -c qemu:///system list
error: Failed to connect socket to '/var/run/libvirt/libvirt-sock': Permission denied
error: failed to connect to the hypervisor

(当前用户没有权限,修改/etc/libvirt/libvirtd.conf,unix_sock_rw_perms = 0777,使所有用户都有权限读写)

 

启动libvirtd进程出错

: /usr/local/sbin/libvirtd -d -l --config /usr/local/etc/libvirt/libvirtd.conf (编译安装的启动方式)

error:/usr/local/sbin/libvirtd: initialization failed

try to install libpcap-devel RPM and rebuild libvirt  http://comments.gmane.org/gmane.comp.emulators.libvirt/58218

apt-get install libpcap-dev

上面的方法好像都没有效果,但是尝试了http://wiki.libvirt.org/page/The_daemon_cannot_be_started说的,把配置文件里的

listen_tls = 0注释取消(更奇怪的问题,在我的客户端链接不对)

 

启动虚拟机:Connection reset by peer

virsh start vm1355991767186
error: Failed to start domain vm1355991767186
error: Unable to read from monitor: Connection reset by peer

 还有可能是这样提示:

error: internal error process exited while connecting to monitor: Failed to allocate 16332619776 B: Cannot allocate memory

这个问题可能是因为为VM分配的内存过大(甚至超过的物理主机的内存大小)

 

Unable to load library 'virt': libvirt.so: cannot open shared object file: No such file or directory

linux 环境:
     ln -s /usr/lib/libvirt.so.0   /usr/lib/libvirt.so
windows 环境
     将libvirt-0.dll改名为virt.dll
  

# virsh undefine vm1354695894990
error: Refusing to undefine while domain managed save image exists

http://www.redhat.com/archives/libvir-list/2011-July/msg01219.html

 managedsave

解决办法:virsh undefine $domain  --managed-save
 
在centos下面Define虚拟机时,确实没有/usr/bin/kvm,加软链接
error: Failed to define domain from xxx.xml
error: Cannot find QEMU binary /usr/bin/kvm: No such file or directory
ln -s /usr/libexec/qemu-kvm /usr/bin/kvm
 
解决办法:ln -s /usr/libexec/qemu-kvm /usr/bin/kvm
