CentOS-6.2
We have a dedicated CentOS-5.7 host used for fax reception
and transmission that we wish to move to a CentOS-6.2
virtual guest instance. The CentOS-6.2 virtual host has a
4-port serial card installed.
lspci -v tshows this this:
03:00.0 Serial controller: Oxford Semiconductor Ltd
OX16PCI954 (Quad 16950 UART) function 0 (Uart) (prog-if 06
[16950])
Subsystem: Oxford Semiconductor Ltd Device 0000
Flags: medium devsel, IRQ 17
I/O ports at d040 [size=32]
Memory at d0702000 (32-bit, non-prefetchable)
[size=4K]
I/O ports at d020 [size=32]
Memory at d0701000 (32-bit, non-prefetchable)
[size=4K]
Capabilities: [40] Power Management version 2
Kernel driver in use: serial
setserial -g /dev/ttyS* shows this:
/dev/ttyS0, UART: 16550A, Port: 0x03f8, IRQ: 4
/dev/ttyS1, UART: 16950/954, Port: 0xd040, IRQ: 17
/dev/ttyS2, UART: 16950/954, Port: 0xd048, IRQ: 17
/dev/ttyS3, UART: 16950/954, Port: 0xd050, IRQ: 17
But, in virt-manage, when I try to add a serial device to
the guest as the physical character device /dev/ttyS1 I
get this error and the device is not added.
XML error: unknown device type
Traceback (most recent call last):
File
"/usr/share/virt-manager/virtManager/addhardware.py",
line 1026, in add_device
self.vm.attach_device(self._dev)

line 698, in attach_device
self._backend.attachDevice(devxml)

line 400, in attachDevice
if ret == -1: raise libvirtError
('virDomainAttachDevice() failed', dom=self)
libvirtError: XML error: unknown device type
We wish to have at least two, preferably three, andf
ideally all four, serial ports enabled on the virtual
guest. Does anyone know how this is accomplished?
