| #9057 | obsolete | Dos slow. >10x compared to other host. VBox GUI slow. | ||
| Description |
i have a boot floppy that simply boots to dos. it includes an archive of utilities in a CAB file. it extracts the contents to a ram drive. i did have a USB HDD connected, and a CD image from the network connected - same if not connected. the decompression runs slow on vbox, like 10x or more slower compared to: i ran same images on a windows 2000 machine (old vbox), although the dos USB drivers caused old vbox to hang, the other FDD image without USB ran fine and faster. 4s for a file compared to >40s. CPU is close to 50%, system is vista ultimate, 4.0.8 vbox also when opening things, ie going to change if the USB HDD is connected or not also causes the lag, so not specifically a virtualization problem. same for choosing the CD or HDD images. the frame appears, the CPU is 50% for a short time then the contents of the "settings" appears. windows XP emulated system seems to run fine. cannot remember if i saw the gui problems earlier, but now i do because DOS is so slow. simply entering C: (return) did nothing and i gave up. cb |

| #9067 | obsolete | Linux kernel warnings when trying to remount a shared folder | ||
| Description |
When I try to remount a shared folder on a Linux guest, it fails and the guest kernel issues several warnings that may indicate that some problem has occured. The steps to reproduce are as follows: First I mount a shared folder "vbshare" to /mnt/shared: #> mount -t vboxsf vbshare /mnt/shared So far so good. Now I try to remount it read only: #> mount -t vboxsf -o remount,ro vbshare /mnt/shared /sbin/mount.vboxsf: mounting failed with the error: Invalid argument In the system log on the guest there are several warnings triggered in the kernel during the execution of sf_read_super_26() (see the attached system.log file for details):
Hardware name: VirtualBox sysfs: cannot create duplicate filename '/devices/virtual/bdi/vboxsf-vbshare'
At the end, the log shows that sf_read_super_aux() returned -EINVAL (-22) and mounting failed indeed.
Guest: Ubuntu 11.04 x64, kernel 2.6.38-8-generic, this problem showed up on other systems too. |
