Virtual box - Συζητήσεις απορείες

[chek2fire]

Ανοίγω αυτό το θέμα για να γράφουμε για τις νέες εκδόσεις του virtual box καθώς και για όποιες απορίες υπάρχουν.

Σήμερα είχαμε την νέα έκδοση του προγράμματος την 2.1. Εντυπωσιακές οι νέες δυνατότες όπως η opengl προσθήκη στα guest συστήματα καθώς και η δυνατότητα να τρέχεις 64 guest σε 32αρη host.

 

 

This version is a major update. The following major new features were added:

 

* Support for hardware virtualization (VT-x and AMD-V) on Mac OS X hosts

* Support for 64-bit guests on 32-bit host operating systems (experimental; see user manual, chapter 1.6, 64-bit guests, page 16)

* Added support for Intel Nehalem virtualization enhancements (EPT and VPID; see user manual, chapter 1.2, Software vs. hardware virtualization (VT-x and AMD-V), page 10))

* Experimental 3D acceleration via OpenGL (see user manual, chapter 4.8, Hardware 3D acceleration (OpenGL), page 66)

* Experimental LsiLogic and BusLogic SCSI controllers (see user manual, chapter 5.1, Hard disk controllers: IDE, SATA (AHCI), SCSI, page 70)

* Full VMDK/VHD support including snapshots (see user manual, chapter 5.2, Disk image files (VDI, VMDK, VHD), page 72)

* New NAT engine with significantly better performance, reliability and ICMP echo (ping) support (bugs #1046, #2438, #2223, #1247)

* New Host Interface Networking implementations for Windows and Linux hosts with easier setup (replaces TUN/TAP on Linux and manual bridging on Windows

Για την δυνατότητα 3d στις guest μηχανές το ενεργοποιήσα σε ένα ubuntu που είχα σε vm αλλά δεν έπαιξε. Θα πρέπει να διαβάσω και το manual να δω τι γίνετε γιατί είναι όντος εντυπωσιακό να έχουμε compiz η να παίζουμε κάποιο 3d παιχνίδι στις virtual machine μας.

NeverWinter Nights 1 σε windows xp virtual machine με kubuntu Ibex host. Το παιχνίδι είναι ένα από τα κλασικά game για windows που τρέχουν σε opengl.

 

 

 

 

Υπάρχει τρελό drop στο frame rate αλλά θα παίξω λίγο με τις ρυθμίσεις μόλις βρω χρόνο μήπως μπορέσω και βελτιώσω την κατάσταση.

Νέα συμαντική έκδοση για το virtual box η 2.2.0

 

This version is a major update. The following major new features were added:

 

* OVF (Open Virtualization Format) appliance import and export (see chapter 3.8, Importing and exporting virtual machines, User Manual page 55)

* Hypervisor optimizations with significant performance gains for high context switching rates

* Raised the memory limit for VMs on 64-bit hosts to 16GB

* VT-x/AMD-V are enabled by default for newly created virtual machines

* USB (OHCI & EHCI) is enabled by default for newly created virtual machines (Qt GUI only)

* Experimental USB support for OpenSolaris hosts

* Shared folders for Solaris and OpenSolaris guests

* OpenGL 3D acceleration for Linux and Solaris guests (see chapter 4.8, Hardware 3D acceleration (OpenGL), User Manual page 70)

In addition, the following items were fixed and/or added:

 

* VMM: FreeBSD guest related fix for V86 flags (bug #2342)

* VMM: fixed guru meditation when booting an AsteriskNow Linux VM (bug #2342)

* VMM: fixed PGMPOOLKIND_FREE guru meditation (bugs #3356, #3431)

* VMM: fixed Windows XP boot hang (guest PAE + nested paging only)

* VMM: allow mixing of VT-x/AMD-V and software virtualization

* VMM: fixed extremely slow safe mode booting in e.g. Windows 2008 (VT-x/AMD-V only)

* VMM: real-mode IOPL fix for DOS guests (VT-x only)

* VMM: fixed VT-x detection with certain BIOSes that enable VT-x, but don’t set the lock bit in MSR_IA32_FEATURE_CONTROL

* VMM: fixed hibernation issues on Windows XP hosts (VT-x only; bug #1794)

* VMM: properly emulate RDMSR from the TSC MSR, should fix some NetBSD guests

* VMM: emulate RDPMC; fixes Windows guests crashes when using the Kaspersky virus scanner (bug #1778)

* NAT: fixed truncated downloads (FTP) (bug #3257)

* NAT: blocked UDP packets caused a crash (bug #3426)

* NAT: allow to configure the next server and the boot file via VBoxManage (bug #2759)

* IDE: fixed hard disk upgrade from XML-1.2 settings (bug #1518)

* Hard disk: support more VMDK file variants (including fixed-size ESX server images)

* Hard disks: refuse to start the VM if a disk image is not writable

* USB: further reduced host CPU utilization for OHCI and EHCI; the “VBoxInternal/Devices/usb-ohci/0/Config/FrameRate” CFG key is no longer necessary and no longer supported

* USB: fixed BSOD on the host with certain USB devices (Windows hosts only; bug #1654)

* E1000: properly handle cable disconnects (bug #3421)

* VRDP: fixed hangs when VRDP server is enabled or disabled in runtime

* Shared folders: respect umask settings on Linux, OSX and Solaris hosts when creating files

* X11 guests: prevented setting the locale in vboxmouse, as this caused problems with Turkish locales (bug #3563)

* X11 guests: show the guest mouse pointer at the right position if the virtual desktop is larger than the guest resolution (bug #2306)

Πλέον μπορούμε να τρέχουμε compiz-fusion στις virtual machine μας!! Ηδη έτρεξα σε ubuntu jaunty που έχω σε μια virtual machine και μιλάμε τρέχει άψογα!!

[chek2fire]

Εχούμε πάει ήδη στην έκδοση 3.0 με συμαντικές αλλαγές και προσθήκες. Ηθελα να κάνω μερικές ερωτήσεις γιατί είχα χαθεί στις ρυθμίσεις του virtual box.

Στις ρυθμίσεις του system έχει μια επιλογή για να βάλεις όσους εικονικούς επεξεργαστές θέλεις. Την έχει δοκιμάσει κανείς και πόσους μπορείς να βάλεις αν έχεις δυπήρινο επεξεργαστή?

Στην ίδια επιλογή από κάτω έχει το enable PAE/NX τι είναι αυτό?

Να προσθέσω ότι βρήκα και ένα bugaki στο παράθυρο επιλογής των iso. Στο φίλτρο έχει τρεις τελείες και δεν σου εμφανίζονται καν τα iso που έχεις αποθηκευμένα σε κάποιον φάκελο. Για να εμφανιστούν θα πρέπει να βάλεις *

[gtroza]

το PAE είναι για να βλέπει φυσικές διευθύνσεις μνήμης πάνω απο 4gb

ΝΧ σημαδεύει κάποιο bit σχετικά μ' αυτή τη δυνατότητα

 

θα τα εξηγήσουν οι καθηγητές αύριο

μάλλον
