#1905 fixed enabling Serial Port throws VERR_PDM_DRIVER_NOT_FOUND Transient
Description

If I enable a serial port in the VM settings I get the error below:


Unknown error creating VM. VBox status code: -2823 (VERR_PDM_DRIVER_NOT_FOUND).

Result Code: 0x80004005 Component: Console Interface: IConsole {d5a1cbda-f5d7-4824-9afe-d640c94c7dcf}


My serial port settings are as follows, although it doesn't seem to matter which port number or path is used:

Port Number: COM1 Port Mode: Host Device Port Path: /dev/tty.serial0

Also, selecting Host Pipe throws a different error.

#1906 fixed clipboard high cpu utilization Bengt-Arne Fjellner
Description

Using rdesktop 1.6.0 to communicate directly with the guest(windows xp) from the host gives high cpu usage even if idle.

Using -r clipboard:off with rdesktop or turning clipboard integration off (VBoxManage) solves it.

So it may only be on in either vbox or rdesktop. Is this possible to detect ? Or at least a warning in the docs might be in place.

#1907 fixed Incorrect bit adjustment in PCIDevSetBaseAddress Aaron Von Gauss
Description

In trying to do some testing with the serial driver, I noticed that there was an incorrect bit adjustment in the PCIDevSetBaseAddress method in "VBox/pci.h". The second bit adjustment is rotating 16 bits while it should be using 8 bits.

    u32Addr = RT_H2LE_U32(u32Addr);
    pPciDev->config[iReg]     = u32Addr         & 0xff;
    pPciDev->config[iReg + 1] = (u32Addr >> 16) & 0xff; /* - */
    pPciDev->config[iReg + 2] = (u32Addr >> 16) & 0xff;
    pPciDev->config[iReg + 3] = (u32Addr >> 24) & 0xff;

The only device in the standard source tree using this code that I'm aware of is the "Audio/DevIchAc97.cpp".
