{toc: } ^ KVM/QEMU ^^ Windows * `agp440.sys` "killed my VMWare XP installation!"<http://support.microsoft.com/kb/324764> * `intelppm.dll` blue screen of death -- http://kvm.qumranet.com/kvmwiki/Windows_ACPI_Workaround * "Install VBEMP x86 Project Universal VESA/VBE Video Display Driver"<http://www.geocities.com/bearwindows/vbemp.htm> to get different resolutions on virtual machine Startup script: .pre # 3M RFID 810 usbdev=0403:6001 sudo chown -R $USER /proc/bus/usb/* kvm -m 512 -hda win-xp.vmdk -no-acpi -std-vga -monitor stdio -usb -usbdevice host:$usbdev .pre ^^ USB sniffing .pre info usbhost .pre ^ VirtualBox * "Windows ACPI problem"<http://www.virtualbox.org/ticket/995> - `agp440.sys` problem ^ OpenVZ ^^ Add disk space to VE First, resize logical volume: .pre root@koha-hw:~# vgextend -L +80G /dev/vg/vz vgextend: invalid option -- L Error during parsing of command line. root@koha-hw:~# lvextend -L +80G /dev/vg/vz Extending logical volume vz to 100.00 GB Logical volume vz successfully resized root@koha-hw:~# resize2fs /dev/vg/vz resize2fs 1.40-WIP (14-Nov-2006) Filesystem at /dev/vg/vz is mounted on /vz; on-line resizing required old desc_blocks = 2, new_desc_blocks = 7 Performing an on-line resize of /dev/vg/vz to 26214400 (4k) blocks. The filesystem on /dev/vg/vz is now 26214400 blocks long. root@koha-hw:~# df -h /vz/ Filesystem Size Used Avail Use% Mounted on /dev/mapper/vg-vz 99G 20G 79G 21% /vz .pre Then, take a look how much space does VEs take: .pre root@koha-hw:~# vzlist -o veid,diskspace,diskspace.s,diskspace.h,diskinodes,diskinodes.s,diskspace.h VEID DQBLOCKS DQBLOCKS.S DQBLOCKS.H DQINODES DQINODES.S DQBLOCKS.H 212052 11717220 15728640 20971520 61001 286527 20971520 212226 6407804 10485760 12582912 69011 435472 12582912 .pre alternativly, you can also execute df inside VEs: .pre root@koha-hw:~# vzlist -o veid -H | xargs -i sh -c "echo --{}-- ; vzctl exec {} df -h" --212052-- Filesystem Size Used Avail Use% Mounted on simfs 15G 12G 3.9G 75% / tmpfs 2.0G 0 2.0G 0% /lib/init/rw tmpfs 2.0G 0 2.0G 0% /dev/shm --212226-- Filesystem Size Used Avail Use% Mounted on simfs 10G 6.2G 3.9G 62% / tmpfs 2.0G 0 2.0G 0% /lib/init/rw tmpfs 2.0G 0 2.0G 0% /dev/shm .pre next, we will set diskpace on both VEs (becase we want them to share all available resources) to new logical volume size: .pre root@koha-hw:~# vzlist -o veid -H | xargs -i vzctl set {} --diskspace 100G:100G --save Saved parameters for VE 212052 Saved parameters for VE 212226 .pre This VEs are not in production, and one is development version of another. When we move to production, we want to enforce more strict limit on disk usage, to protect production machine from running out of disk space in case the development one goes wild. ^ VMWare ^^ Convert image to monolithic growable disk This format is supported by other emulators, so it's a best choice. .pre dpavlin@llin:/rest/vmware/winxp$ vmware-vdiskmanager -r Windows\ XP\ Professional.vmdk -t 0 /mnt/usb/vmware/win-xp.vmdk Using log file /tmp/vmware-dpavlin/vdiskmanager.log Creating a monolithic growable disk '/mnt/usb/vmware/win-xp.vmdk' Convert: 57% done. .pre ^^ Resize disk image .pre dpavlin@llin:/mnt/usb/vmware$ qemu-img info win-xp.vmdk (VMDK) image open: flags=0x2 filename=win-xp.vmdk image: win-xp.vmdk file format: vmdk virtual size: 3.0G (3221225472 bytes) disk size: 3.0G .pre There is a way to extend image using only `qemu-img`, but that involves converting image to raw and appending zeros at end to produce larger image. However, we will do that using VMWare's `vmware-vdiskmanager` .pre dpavlin@llin:/mnt/usb/vmware$ vmware-vdiskmanager -x 6Gb win-xp.vmdk Using log file /tmp/vmware-dpavlin/vdiskmanager.log Grow: 100% done. The old geometry C/H/S of the disk is: 6241/16/63 The new geometry C/H/S of the disk is: 12483/16/63 Disk expansion completed successfully. WARNING: If the virtual disk is partitioned, you must use a third-party utility in the virtual machine to expand the size of the partitions. For more information, see: http://www.vmware.com/support/kb/enduser/std_adp.php?p_faqid=1647 .pre This will make disk unbootable, so we will have to resize partition. Download "GParted"<http://gparted.sourceforge.net/> live CD and resize partition using it... .pre kvm -m 512 -hda win-xp.vmdk -no-acpi -std-vga -cdrom /rest/iso/gparted-live-0.3.9-4.iso -boot d .pre ^^ Convert vmdk to qcow .pre dpavlin@llin:/mnt/usb/vmware$ qemu-img convert -O qcow win-xp.vmdk win-xp.qcow (VMDK) image open: flags=0x2 filename=win-xp.vmdk dpavlin@llin:/mnt/usb/vmware$ ls -al win-xp.* -rw-r--r-- 1 dpavlin dpavlin 3190906880 Oct 9 17:41 win-xp.qcow -rw------- 1 dpavlin dpavlin 3208577024 Oct 9 17:35 win-xp.vmdk .pre |
