Hi, I''m having a strange problem to start a virtual machine PV and would like to know if anyone has experienced this or if it''s a BUG. I have Xen 4.1.4, kernel 2.6.32-xen and CentOS 6.4 64bits, the configuration of my virtual machine like this: VM.xml <domain type=''xen''> <name>vm-1</name> <memory>8097152</memory> <vcpu>4</vcpu> <os> <type arch=''x86_64'' machine=''xenpv''>linux</type> </os> <features> <acpi/> <apic/> <pae/> </features> <clock offset=''utc''> <timer name=''hpet'' present=''no''/> </clock> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>restart</on_crash> <devices> <disk type=''file'' device=''disk''> <driver name=''tap2'' type=''vhd'' /> <source file=''/local/disk/vm-1.vhd'' /> <target dev=''xvda'' bus=''xen'' /> </disk> <interface type=''bridge''> <mac address=''00:16:3e:19:25:fa''/> <source bridge=''virtbr12''/> <script path=''/etc/xen/scripts/vif-test''/> <target dev=''tec002.0''/> </interface> <interface type=''bridge''> <mac address=''ce:65:82:e3:ec:7d''/> <source bridge=''virtbr4''/> <script path=''/etc/xen/scripts/vif-test''/> <target dev=''tec004.0''/> </interface> <graphics type=''vnc'' autoport=''yes''/> </devices> </domain> Sometimes I get this error message: error: POST operation failed: xend_post: error from xen daemon: (xend.err "Error creating domain: Disk isn''t accessible") Searching in the internet, I found this link, http://comments.gmane.org/gmane.os.solaris.opensolaris.xen/5105, took the test and it worked, but when you restart the virtual machine, not started, and went back to have problems with "Error creating domain: Disk isn''t accessible" Checked that this virtual machine disk mapped to the dom0. # virsh dumpxml 0 <domain type=''xen'' id=''0''> <name>Domain-0</name> <uuid>00000000-0000-0000-0000-000000000000</uuid> <memory>4194304</memory> <currentMemory>3702784</currentMemory> <vcpu cpuset=''0-3''>4</vcpu> <bootloader></bootloader> <os> <type>linux</type> </os> <clock offset=''utc''/> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>restart</on_crash> <devices> <disk type=''file'' device=''disk''> <driver name=''tap2'' type=''vhd''/> <source file=''/local/disk/vm-1.vhd''/> <target dev=''/dev/xvdp'' bus=''ide''/> <readonly/> </disk> <disk type=''file'' device=''disk''> <driver name=''tap2'' type=''vhd''/> <source file=''/root/vm-1/vm-1.vhd''/> <target dev=''/dev/xvdp'' bus=''ide''/> <readonly/> </disk> </devices> </domain> How can I remove this mapping to dom0? How to fix this problem? Regards, Marcos Amorim _______________________________________________ Xen-users mailing list Xen-users@lists.xen.org http://lists.xen.org/xen-users
