[et-mgmt-tools] [PATCH] HVM 3rd disk name don't use "hdc"

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi

I try that making the HVM domain with 3+ disks by the virt-install command,
but the command says following error message:
# virt-install --name=HVM_3DISKS --file=/dev/sda6 --file=/dev/sda7 \
 --file=/dev/sda8 --hvm --vnc --ram=376 --cdrom=/dev/cdrom

libvir: Xen Daemon error : POST operation failed: (xend.err 'Error
creating domain: Device hdc (5632, vbd) is already connected.')
Traceback (most recent call last):
  File "/usr/bin/virt-install", line 584, in <module>
    main()
  File "/usr/bin/virt-install", line 544, in main
    dom = guest.start_install(conscb,progresscb)
  File "/usr/lib/python2.5/site-packages/virtinst/Guest.py", line 626,
in start_install
    return self._do_install(consolecb, meter)
  File "/usr/lib/python2.5/site-packages/virtinst/Guest.py", line 643,
in _do_install
    self.domain = self.conn.createLinux(install_xml, 0)
  File "/usr/lib/python2.5/site-packages/libvirt.py", line 429, in
createLinux
    if ret is None:raise libvirtError('virDomainCreateLinux() failed',
conn=self)
libvirt.libvirtError: virDomainCreateLinux() failed POST operation
failed: (xend.err 'Error creating domain: Device hdc (5632, vbd) is
already connected.')

I think that the 3rd disk's name "hdc" is conflicted CDROM device name.

I make the patch resolve this issue.
