VirtualBox 3.1.0

Pojawiła się maszynka w aktualizacjach i aż zdziwiłem się, że newsa nie ma na osnews, a tu po chwili się pojawił i to nie byle jaki ;]

Ostatnio zainteresowałem się wirtualizacja na Linuksie, w sumie bardziej z przymusu niż z dobrej woli, ale mniejsza o to… Wciąż jestem "świeżakiem" w tym temacie, ale stara, się nadrabiać zaległości

Najbardziej znane są dwa produkty VMware Workstation i VirtualBox. Problem w tym, że w obu boleśnie odczuwam spadek wydajności…

Skoro już używam wirtualizacji, to zastanawia mnie czy nie da się tego robić lepiej niż VirtualBox? Komputery, na których pracuję mają procesory Intela z obsługą VT-x i 4GB RAMu, więc maja potencjał…

Jak wygląda sprawa z Xen, QEMU i KVM? Obiecująco wygląda KVM i QEMU z akceleratorem kqemu, ale nie są tak user-friendly jak VB i produkt VMware. Jeżeli macie jakieś _rzetelne_ artykuły/strony na temat wirtualizacji pod linuksem będę wdzięczny!

Pozdrawiam!

U mnie ciągle nie działa prawidłowo 3D w systemie guesta jeśli guest to Linux i host to Linux a konkretnie guest to Ubuntu a host to Debian. Działa 3D ale zawartość okna z uruchomionym guestem "dziwnie" się zachowuje – migoce, znika, pojawia się kiedy ruszę myszką itp. Jeśli host to Windows (Vista) a guest to Linux wszystko jest OK – widziałem u kolegi na laptopie.

Ale i tak uważam VirtualBokxa za kawał niezłego softu . Kilka kliknięć myszką i możesz mieć swoją wirtualną maszynę – udało mi się już uruchomić i przetestować dzięki niemu Haiku, Debiana/kFreeBSD, nie mówiąc o Windowsie XP .

Jeżeli jest EFI oznacza to że można spróbować instalacji Mac OS X?

A mi do pełni szczęścia brakuje bezpośredniego dostępu do urządzeń blokowych.

Wbrew opinii niektórych VirtualBox to nie jest zabawka. A pojęcie, że poważniejsze zastosowania wirtualizacji to serwery jest śmieszne.

Ja w pracy – szczególnie przy rozwoju aplikacji desktop/web – używam VirtualBox bardzo często jako wirtualny desktop do testów (testuję aplikację pod różnymi systemami/przeglądarkami) i jak dla mnie (i nie tylko dla mnie) sprawdza się super. Jest to świetna darmowa alternatywa dla np. vmWare Workstation.

W porównaniu do konkurencji na rynku desktopowych (ładnych, wygodnych, kolorowych, łatwych w użyciu itd:) VirtualBox ma tą miażdżącą zaletę nad konkurencją, że rozwija się w błyskawicznym tempie. Kolejne wersje wychodzą naprawdę bardzo często i każdy kolejny numerek niesie ze sobą rzeczywiście coś nowego. Także polecam wszystkim!

Fajnie, a można już zmieniać adresy, które wirtualne maszyny dostają z DHCP?

Nikt nie mówi o ESXi, który jest darmowy i instaluje się na bare metal jako bardzo lekki host. U nas sprawdza się znakomicie. Niestety nie robiłem testów porównawczych. Od 2 lat nie zaliczyłem żadnych problemów. Intuicyjny interfejs i dość obszerne opcje monitoringu wydajności i zarządzania zasobamy.

ESXi jest bardzo dobrym rozwiazaniem – niestety w przypadku wiekszej ilosci host'ow i guest'ow brakuje w nim spojnej metody zarzadzania tym wszystkiem.

Wiem, to nie jest rozwiazanie enterprise – wiec nie powinienem czegos takiego oczekiwac.

Uzywam zarowno XEN Server jak i ESXi do wirtualizacji okolo 200 maszyn, oba sprawdzaja sie dobrze i stabilnie. W zaleznosci od potrzeb czasem jeden jest lepszy, czasem drugi. Jest to ogolna informacja – ale nie jest to tez forum do relizowania porowania – szczegolnie ze temat postu dotyczy virtualboxa

Pozdr,

-M.

Ostatnio chciałbym się zabawić w virtualboxie… mianowicie chce w nim zainstalowac Win98 i sprawdzić na ile szybko niezabezpieczony zlapie jakiś syf. Ale mam obawy… dotyczące tego iż nie wiem na ile bezpieczny jest mój podstawowy system. Czy wirus, trojan który zagnieżdzi się w wirtualnym systemie nie mma szans przejść na normalny system (nie wirtualny). Tak samo jeśli jakiś haker mający dostęp do wirtualnej maszyny nie wejdzie na podstawowy? Mógłby ktoś rozwiać moje wątpliwości? VirtualBox zainstalowany jest na Viście

P.S. Wybaczcie że nie używam "profesjonalnego" słownictwa, ale w tej tematyce jestem zielony

Where might I see the same wordpress guide like this one? is it compatible with the present-day 3.1? thanks

There’s a error with your sidebar.. supposed you would likely wanna recognize

One other thing I would like to say is that in lieu of trying to match all your online degree training on days and nights that you finish work (since most people are tired when they get home), try to find most of your lessons on the weekends and only a couple courses in weekdays, even if it means taking some time off your weekend break. This pays off because on the weekends, you will be much more rested as well as concentrated in school work. Thanks alot : ) for the different ideas I have realized from your blog site.

I believe avoiding ready-made foods may be the first step for you to lose weight. They will often taste fine, but ready-made foods include very little vitamins and minerals, making you feed on more only to have enough vigor to get throughout the day. For anyone who is constantly feeding on these foods, switching to whole grains and other complex carbohydrates will let you have more vitality while consuming less. Great blog post.

Hmm it seems like your site ate my first comment (it was extremely long) so I guess I’ll just sum it up what I submitted and say, I’m thoroughly enjoying your blog. I as well am an aspiring blog blogger but I’m still new to everything. Do you have any suggestions for first-time blog writers? I’d genuinely appreciate it.

Cleaning soap and training usually are not as sudden as a bloodbath, however they’re extra deadly in the lengthy run.

Between me and my husband we’ve owned more MP3 players over the years than I can count, including Sansas, iRivers, iPods (classic & touch), the Ibiza Rhapsody, etc. But, the last few years I’ve settled down to one line of players. Why? Because I was happy to discover how well-designed and fun to use the underappreciated (and widely mocked) Zunes are.

Great site here. So many websites like yours cover subjects that can’t be found in print. I don’t know how we got on 10 years ago with just magazines and newspapers.

My mortgage company still did not pay my taxes for just two years. Now I am paying for it! I was advised to measure each year to see if they were paying them. How do you do that?

The nuclear situation is bad but NOT critical. Remember they had nuclear bombs in Hiroshima and Nagaski in Japan which ended WW2.

Could I use part of the information from the post previously mentioned if I give a backlink for your site?

What an enjoyable (and may I say insightful) read! You may not know it, but this post of yours gave me so many realizations. I wonder if it occurs to you and other people, too, but there are times when I get wonderful ideas from things that don’t have anything to do at all with what’s in my mind. On a different note, I read a lot of blogs, it’s what I do before I head off to the gym, and I can’t believe some of the trash that some people are putting out, like a magic bullet for this, and a so-called-secret for that. Like in the topic of body-building, I’ve read quite a number of blogs that talk about products that make building muscles almost instantaneous! Imagine, bodybuilding without breaking a sweat?! Come on! At the very least you need to have a workout program which you will actually follow! Now I’m ranting, sorry. I’ll look around your blog some more before heading to another one.

Great thanks

I like the efforts you have put in this, thanks for all the great articles.

Thanks for the post. Can you please send me few more articles about this, I am really a fan of your blog. Thanks, Jeremiah Allison

The following time I read a blog, I hope that it doesnt disappoint me as a lot as this one. I imply, I know it was my option to read, but I truly thought youd have one thing fascinating to say.
