18.24. 解​​​​​​​釋​​​​​​​錯​​​​​​​誤​​​​​​​訊​​​​​​​息​​​​​​​

您​​​​​​​收​​​​​​​到​​​​​​​下​​​​​​​列​​​​​​​錯​​​​​​​誤​​​​​​​： 
failed domain creation due to memory shortage, unable to balloon domain0
網​​​​​​​域​​​​​​​可​​​​​​​能​​​​​​​會​​​​​​​因​​​​​​​為​​​​​​​ RAM 不​​​​​​​足​​​​​​​而​​​​​​​失​​​​​​​敗​​​​​​​。​​​​​​​如​​​​​​​果​​​​​​​空​​​​​​​間​​​​​​​ domain0 無​​​​​​​法​​​​​​​增​​​​​​​加​​​​​​​足​​​​​​​夠​​​​​​​的​​​​​​​空​​​​​​​間​​​​​​​來​​​​​​​新​​​​​​​建​​​​​​​立​​​​​​​客​​​​​​​座​​​​​​​端​​​​​​​。​​​​​​​您​​​​​​​可​​​​​​​以​​​​​​​檢​​​​​​​查​​​​​​​ xend.log 來​​​​​​​找​​​​​​​出​​​​​​​這​​​​​​​個​​​​​​​錯​​​​​​​誤​​​​​​​： 
[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.
您​​​​​​​收​​​​​​​到​​​​​​​下​​​​​​​列​​​​​​​錯​​​​​​​誤​​​​​​​： 
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.
輸​​​​​​​入​​​​​​​這​​​​​​​個​​​​​​​指​​​​​​​令​​​​​​​：

如​​​​​​​果​​​​​​​您​​​​​​​需​​​​​​​要​​​​​​​執​​​​​​​行​​​​​​​ 32 位​​​​​​​元​​​​​​​或​​​​​​​是​​​​​​​非​​​​​​​ PAE 核​​​​​​​心​​​​​​​，您​​​​​​​必​​​​​​​須​​​​​​​執​​​​​​​行​​​​​​​以​​​​​​​完​​​​​​​整​​​​​​​虛​​​​​​​擬​​​​​​​化​​​​​​​虛​​​​​​​擬​​​​​​​主​​​​​​​機​​​​​​​來​​​​​​​執​​​​​​​行​​​​​​​客​​​​​​​座​​​​​​​端​​​​​​​。​​​​​​​至​​​​​​​於​​​​​​​半​​​​​​​虛​​​​​​​擬​​​​​​​化​​​​​​​客​​​​​​​座​​​​​​​端​​​​​​​，如​​​​​​​果​​​​​​​您​​​​​​​需​​​​​​​要​​​​​​​執​​​​​​​行​​​​​​​ 32 位​​​​​​​元​​​​​​​ PAE 客​​​​​​​座​​​​​​​端​​​​​​​，則​​​​​​​您​​​​​​​必​​​​​​​須​​​​​​​擁​​​​​​​有​​​​​​​ 32 位​​​​​​​元​​​​​​​ PAE 管​​​​​​​理​​​​​​​程​​​​​​​序​​​​​​​；如​​​​​​​果​​​​​​​您​​​​​​​需​​​​​​​要​​​​​​​執​​​​​​​行​​​​​​​ 64 位​​​​​​​元​​​​​​​ PAE 客​​​​​​​座​​​​​​​端​​​​​​​，則​​​​​​​您​​​​​​​必​​​​​​​須​​​​​​​擁​​​​​​​有​​​​​​​ 64 位​​​​​​​元​​​​​​​管​​​​​​​理​​​​​​​程​​​​​​​序​​​​​​​。​​​​​​​對​​​​​​​於​​​​​​​完​​​​​​​整​​​​​​​虛​​​​​​​擬​​​​​​​化​​​​​​​客​​​​​​​座​​​​​​​端​​​​​​​您​​​​​​​必​​​​​​​須​​​​​​​在​​​​​​​ 64 位​​​​​​​元​​​​​​​管​​​​​​​理​​​​​​​程​​​​​​​序​​​​​​​上​​​​​​​執​​​​​​​行​​​​​​​ 64 位​​​​​​​元​​​​​​​客​​​​​​​座​​​​​​​端​​​​​​​。​​​​​​​RHEL 5 i686 的​​​​​​​ 32 位​​​​​​​元​​​​​​​ PAE 管​​​​​​​理​​​​​​​程​​​​​​​序​​​​​​​僅​​​​​​​支​​​​​​​援​​​​​​​ 32 位​​​​​​​元​​​​​​​ PAE 半​​​​​​​虛​​​​​​​擬​​​​​​​化​​​​​​​與​​​​​​​ 32 位​​​​​​​元​​​​​​​完​​​​​​​整​​​​​​​虛​​​​​​​擬​​​​​​​化​​​​​​​客​​​​​​​座​​​​​​​端​​​​​​​作​​​​​​​業​​​​​​​系​​​​​​​統​​​​​​​。​​​​​​​64 位​​​​​​​元​​​​​​​管​​​​​​​理​​​​​​​程​​​​​​​序​​​​​​​僅​​​​​​​支​​​​​​​援​​​​​​​ 64 位​​​​​​​元​​​​​​​半​​​​​​​虛​​​​​​​擬​​​​​​​化​​​​​​​客​​​​​​​座​​​​​​​端​​​​​​​。​​​​​​​
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.
您​​​​​​​收​​​​​​​到​​​​​​​下​​​​​​​列​​​​​​​錯​​​​​​​誤​​​​​​​： 
Unable to open a connection to the Xen hypervisor or daemon
這​​​​​​​會​​​​​​​在​​​​​​​ virt-管​​​​​​​理​​​​​​​應​​​​​​​用​​​​​​​程​​​​​​​式​​​​​​​啟​​​​​​​動​​​​​​​失​​​​​​​敗​​​​​​​時​​​​​​​發​​​​​​​生​​​​​​​。​​​​​​​在​​​​​​​ /etc/hosts 設​​​​​​​定​​​​​​​檔​​​​​​​案​​​​​​​中​​​​​​​沒​​​​​​​有​​​​​​​本​​​​​​​地​​​​​​​主​​​​​​​機​​​​​​​項​​​​​​​目​​​​​​​時​​​​​​​，這​​​​​​​個​​​​​​​錯​​​​​​​誤​​​​​​​便​​​​​​​會​​​​​​​發​​​​​​​生​​​​​​​。​​​​​​​如​​​​​​​果​​​​​​​本​​​​​​​地​​​​​​​主​​​​​​​機​​​​​​​項​​​​​​​目​​​​​​​為​​​​​​​啟​​​​​​​動​​​​​​​，請​​​​​​​檢​​​​​​​查​​​​​​​該​​​​​​​檔​​​​​​​案​​​​​​​。​​​​​​​下​​​​​​​列​​​​​​​為​​​​​​​一​​​​​​​個​​​​​​​不​​​​​​​正​​​​​​​確​​​​​​​的​​​​​​​本​​​​​​​地​​​​​​​主​​​​​​​機​​​​​​​項​​​​​​​目​​​​​​​之​​​​​​​例​​​​​​​子​​​​​​​： 
# Do not remove the following line, or various programs
# that require network functionality will fail.
localhost.localdomain localhost
下​​​​​​​列​​​​​​​為​​​​​​​正​​​​​​​確​​​​​​​本​​​​​​​地​​​​​​​主​​​​​​​機​​​​​​​項​​​​​​​目​​​​​​​之​​​​​​​例​​​​​​​子​​​​​​​： 
# 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
您​​​​​​​會​​​​​​​收​​​​​​​到​​​​​​​下​​​​​​​列​​​​​​​錯​​​​​​​誤​​​​​​​訊​​​​​​​息​​​​​​​（於​​​​​​​ xen-xend.log file 中​​​​​​​）： 
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

此​​​​​​​外​​​​​​​，xend.log 會​​​​​​​顯​​​​​​​示​​​​​​​下​​​​​​​列​​​​​​​錯​​​​​​​誤​​​​​​​訊​​​​​​​息​​​​​​​：

欲​​​​​​​解​​​​​​​決​​​​​​​這​​​​​​​個​​​​​​​問​​​​​​​題​​​​​​​，您​​​​​​​必​​​​​​​須​​​​​​​編​​​​​​​輯​​​​​​​您​​​​​​​的​​​​​​​客​​​​​​​座​​​​​​​端​​​​​​​設​​​​​​​定​​​​​​​檔​​​​​​​，並​​​​​​​修​​​​​​​改​​​​​​​ vif 項​​​​​​​目​​​​​​​。​​​​​​​當​​​​​​​您​​​​​​​找​​​​​​​到​​​​​​​設​​​​​​​定​​​​​​​檔​​​​​​​的​​​​​​​ vif 項​​​​​​​目​​​​​​​，請​​​​​​​將​​​​​​​ xenbr0 視​​​​​​​為​​​​​​​預​​​​​​​設​​​​​​​橋​​​​​​​接​​​​​​​，確​​​​​​​保​​​​​​​正​​​​​​​確​​​​​​​項​​​​​​​目​​​​​​​類​​​​​​​似​​​​​​​於​​​​​​​下​​​​​​​列​​​​​​​： 
# vif = ['mac=00:16:3e:49:1d:11, bridge=xenbr0',]
您​​​​​​​收​​​​​​​到​​​​​​​這​​​​​​​些​​​​​​​ python 錯​​​​​​​誤​​​​​​​：

Python 在​​​​​​​設​​​​​​​定​​​​​​​檔​​​​​​​為​​​​​​​無​​​​​​​效​​​​​​​（或​​​​​​​不​​​​​​​正​​​​​​​確​​​​​​​）時​​​​​​​會​​​​​​​產​​​​​​​生​​​​​​​這​​​​​​​些​​​​​​​訊​​​​​​​息​​​​​​​。​​​​​​​欲​​​​​​​解​​​​​​​決​​​​​​​這​​​​​​​個​​​​​​​問​​​​​​​題​​​​​​​，您​​​​​​​必​​​​​​​須​​​​​​​修​​​​​​​正​​​​​​​不​​​​​​​正​​​​​​​確​​​​​​​的​​​​​​​設​​​​​​​定​​​​​​​檔​​​​​​​，或​​​​​​​者​​​​​​​您​​​​​​​可​​​​​​​以​​​​​​​建​​​​​​​立​​​​​​​一​​​​​​​個​​​​​​​新​​​​​​​的​​​​​​​設​​​​​​​定​​​​​​​檔​​​​​​​。​​​​​​​
