My Open Source Virtualization talk

1. Open Source Virtualization An overview Kris Buytaert [email_address]

3. „ Infrastructure Architect“

4. Linux since 0.98

5. OpenMosix, openQRM, ...

6. Early Adopter (Xen, MySQL Cluster)

7. Automating Large Scale Deployment , High Availability

8. Surviving the 10 th floor test

9. CoAuthor of Virtualization with Xen

13. Virtualization vs Virtualization

14. Where we come from

15. Now and Xen

16. Managing Virtual Machines

17. Where are we heading ? Agenda

19. separate an operating system from the underlying platform resources What is Virtualization ?

21. Saving Idle Cycles

22. Security

23. Separating Development/Staging/Production platforms

24. Hardware Independence

25. A Greener Environment

26. Having a budget that needs to be emptied.

27. All the cool kids are doing it Why Virtualization Matters

32. Hard to get strong isolation

33. Typically used for Hosting/Virtual Hosting/ISP

34. Run a lot of almost identical Virtual Machines

35. 1 single kernel Chroot’s on steroids Virtualization vs Virtualization

37. Hard to efficiently virtualize x86

38. No Access to the hardware

39. No Realtime guarantees

40. Problematic for certain privileged instructions Virtualization vs Virtualization

42. Arch Xen/x86 is very close to normal x86

43. Some Access to underlying hardware

44. Better Performance

45. Needs modification to the OS Virtualization vs Virtualization

47. KVM

49. Hardware solves the problem Virtualization vs Virtualization

51. First Virtualization Aquisition Ever ? Looking back at a decade of Virtualization

54. For those unfamiliar with my background, I authored a full x86 PC emulation project in the 1990's, called bochs. It was used in one form or another, by a number of virtualization players, including an R&D project at Stanford which became Vmware. Kevin Lawton on his blog march 2009 Looking back at a decade of Virtualization

56. Win4Lin

57. Wine Oldskool Emulation

60. VmWare View: Open Source Client Is this Virtualization ?

62. Mainly to run test scenarios

63. Rebranded later to Faumachine The land of Confusion:

66. Chroot on steroids More Land of Confusion

68. According to the developers no shared codebase OpenVZ , LinuxVServer

70. Virtuozzo 2001

71. 2003 Swsoft buys Plesk

72. SWSoft buys Parallels but “forgets” to tell

73. Eventually rebrands to Parallels late 2007

74. Kernel Inclusion ? OpenVZ , Virtuozzo

77. Lhype

78. WonkyVisor

79. RustyVisor

84. Open Source

85. VMWare alternative

86. Great Desktop Support

87. Bought by Sun (just before Fosdem 2008)

88. Now part of the xVM suite Virtualbox

90. Pioneered VT support

91. Went Mainstream real fast !

92. Stable and performant platform

93. Scriptable

95. Open Source

96. Known Developers

97. Event Channel Virtual MMU Virtual CPU Control IF Hardware (SMP, MMU, physical memory, Ethernet, SCSI/IDE) Native Device Driver GuestOS (XenLinux) Device Manager & Control s/w Native Device Driver GuestOS (XenLinux) Unmodified User Software Front-End Device Drivers GuestOS (XenLinux) Unmodified User Software Front-End Device Drivers Unmodified GuestOS (WinXP)) Unmodified User Software Safe HW IF Xen Virtual Machine Monitor Back-End Back-End VT-x AGP ACPI PCI SMP

100. Fighting over “stability”

106. VT Required

107. “just a module”

108. /usr/local/kvm/bin/qemu-*

109. Came out of nowhere

110. +/- 6 weeks before kernel inclusion

111. Since 2.6.20

112. Lean and Mean

113. Desktop Oriented KVM

115. Proprietary Own protocol

118. Libvirt

119. Ovirt

120. OpenQRM Managing Your Virtualization Platform

122. OpenNebula

123. OpenQRM

124. Nimbus

125. SnowFlock

126. Eucalyptus Building your own cloud

130. Support for physical , Xen, VMWare, Vserver, KVM

131. OpenQRM 4 is a full rewrite

134. a root-file system (local, NFS, ISCSI)

139. KVM @ RedHat

140. OpenVZ in the Kernel ?

141. Xen in the Kernel ?

142. Oracle buying Virtual Iron ? The Future
