Configuring Virtual Devices
Managing Virtual Machines and Containers
In Parallels Server Bare Metal, you can use the --device-set option of the pctl set
command to configure the parameters of an existing virtual device. As a rule, the process of
configuring the device properties includes two steps:
1 Finding out the name of the device you want to configure.
2 Running the pctl set command to configure the necessary device properties.
Finding Out Device Names
To configure a virtual device, you need to specify its name when running the pctl set command.
If you do not know the device name, you can use the pctl list command to learn it. For
example, to obtain the list of virtual devices in the MyVM virtual machine, run this command:
# pctl list --info MyVM
...
Hardware:
cpu 2 VT-x accl=high mode=32
memory 256Mb
video 46Mb
fdd0 (+) real='/dev/fd0' state=disconnected
hdd0 (+) sata:0 image='/var/parallels/MyVM.pvm/harddisk.hdd' 27000Mb
hdd1 (+) scsi:0 image='/var/parallels/MyVM.pvm/harddisk1.hdd' 32768Mb
cdrom0 (+) ide:1 real='Default CD/DVD-ROM'
parallel0 (+) real='/dev/lp0'
usb (+)
net0 (+) type=bridged iface='eth1' mac=001C4201CED0
...
All virtual devices currently available to the virtual machine are listed under Hardware. In our case
the MyVM virtual machine has the following devices: 2 CPUs, main memory, video memory, a floppy
disk drive, 2 hard disk drives, a CD/DVD-ROM drive, a parallel port, a USB controller, and a
network card.
Configuring Virtual Devices
Once you know the virtual device name, you can configure its properties. For example, you can
execute the following command to configure the current type of the virtual disk hdd1 in the MyVM
virtual machine from SATA to SCSI:
# pctl set MyVM --device-set hdd1 --iface scsi
The VM has been successfully configured.
To check that the virtual disk type has been successfully changed, use the pctl list --info
command:
# pctl list --info MyVM
...
hdd0 (+) scsi:1 image='/var/parallels/MyVM.pvm/harddisk.hdd' 85000Mb
