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?

Marcos Amorim
