18.24. 翻译错误信息
你接收到下面的错误：
failed domain creation due to memory shortage, unable to balloon domain0
如果没有足够的可用内存，域将不能运行。Domain0 没有足够的空间来容纳新创建的客户机。你可以检查
xend.log 里关于这个错误的内容：
[2006-12-21] 20:33:31 xend 3198] DEBUG (balloon:133) Balloon: 558432 Kib free; 0 to scrub; need 1048576; retries: 20 [2006-12-21] 20:33:31 xend. XendDomainInfo 3198] ERROR (XendDomainInfo: 202 Domain construction failed
You can check the amount of memory in use by domain0 by using the
xm list Domain0 command. If domain0 is not ballooned down, you can use the command "xm mem-set Domain-0 NewMemSize" to check memory.
你接收到下面的错误：
wrong kernel image: non-PAE kernel on a PAE
This message indicates that you are trying to run an unsupported guest kernel image on your Hypervisor. This happens when you try to boot a non-PAE paravirtual guest kernel on a RHEL 5.1 hypervisor. Red Hat Virtualization only supports guest kernels with PAE and 64bit architectures.
键入这个命令：
[root@smith]# xm create -c va base Using config file "va-base" Error: (22, 'invalid argument') [2006-12-14 14:55:46 xend.XendDomainInfo 3874] ERRORs (XendDomainInfo:202) Domain construction failed Traceback (most recent call last) File "/usr/lib/python2.4/site-packages/xen/xend/XendDomainInfo.py", line 195 in create vm.initDomain() File " /usr/lib/python2.4/site-packages/xen/xend/XendDomainInfo.py", line 1363 in initDomain raise VmError(str(exn)) VmError: (22, 'Invalid argument') [2006-12-14 14:55:46 xend.XendDomainInfo 3874] DEBUG (XenDomainInfo: 1449] XendDlomainInfo.destroy: domin=1 [2006-12-14 14:55:46 xend.XendDomainInfo 3874] DEBUG (XenDomainInfo: 1457] XendDlomainInfo.destroy:Domain(1)
如果你需要运行 32 位/非 PAE 内核，你将需要把客户机作为完全虚拟化的虚拟机运行。对于半虚拟化的客户机，如果你需要运行 32 位的 PAE 客户机，你必须具有 32 位的 PAE 监控程序。对于半虚拟化的客户机，如果你要运行 64 位的 PAE 客户机，你必须具有 64 位的 PAE 监控程序。对于完全虚拟化的客户机，你必须用 64 位的监控程序运行 64 位客户机。RHEL 5 i686 里的 32 位 PAE 监控程序只支持运行 32 位的并行虚拟化和 32 位的完全虚拟化的客户机操作系统。64 位监控程序只支持 64 位的并行虚拟化客户机。
This happens when you move the full virtualized HVM guest onto a RHEL 5.1 system. Your guest may fail to boot and you will see an error in the console screen. Check the PAE entry in your configuration file and ensure that pae=1.You should use a 32bit distibution.
你接收到下面的错误：
Unable to open a connection to the Xen hypervisor or daemon
当 virt-manager 程序不能启动时，会出现这个问题。当
/etc/hosts 配置文件里没有 localhost 条目时会产生这个错误。请确认配置文件里是否启用了 localhost 条目。下面是一个错误的 localhost 条目示例：
# Do not remove the following line, or various programs # that require network functionality will fail. localhost.localdomain localhost
下面是一个正确的 localhost 条目示例：
# Do not remove the following line, or various programs # that require network functionality will fail. 127.0.0.1 localhost.localdomain localhost localhost.localdomain. localhost
你会接收到下面的错误（在
xen-xend.log file 文件里）：
Bridge xenbr1 does not exist!
This happens when the guest's bridge is incorrectly configured and this forces the Xen hotplug scipts to timeout. If you move configuration files between hosts, you must ensure that you update the guest configuration files to reflect network topology and configuration modifications. When you attempt to start a guest that has an incorrect or non-existent Xen bridge configuration, you will receive the following errors:
[root@trumble virt]# xm create r5b2-mySQL01 Using config file " r5b2-mySQL01" Going to boot Red Hat Enterprise Linux Server (2.6.18.-1.2747 .el5xen) kernel: /vmlinuz-2.6.18-12747.el5xen initrd: /initrd-2.6.18-1.2747.el5xen.img Error: Device 0 (vif) could not be connected. Hotplug scripts not working.
另外，
xend.log 里会有下面的错误：
[2006-11-14 15:07:08 xend 3875] DEBUG (DevController:143) Waiting for devices vif [2006-11-14 15:07:08 xend 3875] DEBUG (DevController:149) Waiting for 0 [2006-11-14 15:07:08 xend 3875] DEBUG (DevController:464) hotplugStatusCallback /local/domain/0/backend/vif/2/0/hotplug-status [2006-11-14 15:08:09 xend.XendDomainInfo 3875] DEBUG (XendDomainInfo:1449) XendDomainInfo.destroy: domid=2 [2006-11-14 15:08:09 xend.XendDomainInfo 3875] DEBUG (XendDomainInfo:1457) XendDomainInfo.destroyDomain(2) [2006-11-14 15:07:08 xend 3875] DEBUG (DevController:464) hotplugStatusCallback /local/domain/0/backend/vif/2/0/hotplug-status
要解决这个问题，你必须编辑你的客户机配置文件，并修改
vif 条目。找到配置文件里的 vif 条目，假定你把 xenbr0 作为缺省网桥，正确的设置应该如下所示：
# vif = ['mac=00:16:3e:49:1d:11, bridge=xenbr0',]
你接收到这些 python 错误：
[root@python xen]# xm shutdown win2k3xen12 [root@python xen]# xm create win2k3xen12 Using config file "win2k3xen12". /usr/lib64/python2.4/site-packages/xenxm/opts.py:520: Deprecation Warning: Non ASCII character '\xc0' in file win2k3xen12 on line 1, but no encoding declared; see http://www.python.org/peps/pep-0263.html for details execfile (defconfig, globs, locs,) Error: invalid syntax 9win2k3xen12, line1)
当遇到无效的（或不正确的）配置文件时，Python 生成这些错误。要解决这个问题，你必须更正不正确的配置文件，或者生成一个新的文件。
