9. TroubleShooting

9.1 리눅스 배포판에 Xen dom0 커널이 포함되어 있는지 확인 방법
http://wiki.xensource.com/xenwiki/XenDom0Kernels 사이트에서 리눅스 배포판별로 XEN-Dom0커널을 기본으로 지원하는지에 대한 정보들을 확인할 수 있다.
아래는 2009년 11월 기준으로 페도라 배포판에 대한 정보이다.
- Fedora
* Fedora 8 is currently the latest release to include Xen dom0 kernel.
* Fedora 9, 10, 11 and 12 do not contain Xen dom0 kernels (but they do contain Xen hypervisor and tools and Xen domU enabled kernels).
* Fedora is planning to add support for Xen dom0 again when pv_ops dom0 is included in the upstream kernel.org Linux kernels.
* For more information: http://fedoraproject.org/wiki/Features/XenPvopsDom0
* M A Young is building unofficial pv_ops Xen dom0 kernel RPMs for Fedora. Download: http://fedorapeople.org/~myoung/dom0/
* See fedora-xen and/or fedora-virt mailinglist archives for more information.

9.1 Error: Unable to connect to xend: No such file or directory. Is xend running? 에러 해결방법
#> /etc/init.d/xend status 명령을 이용하여 xend 서비스가 실행중인지 체크하도록 한다.

이상.

* 오픈소스는 Open Innovationa & 윈윈전략을 도모할 지언정 절대 공짜(무료)임을 뜻하지 않는다.치

  참고로, 페도라 11,12와 같은 최신 배포판의 커널은 "Xen privileged domain support "피쳐를 내장하고 있지않으므로,
  
  XEN을 Host으로 사용할수 없다. 따라서 필자의 경우에는 페도라 11,12에서 페도라 6,7의 리눅스 커널소스를 재빌드
  
  하여 사용하거나 기본으로 내장되어 있는 RHEL의 무료판인 CENTOS 5.X를 주로 이용하는 편이다.
