Virtual operating systems, virtual machines

Sit tight, Linux Users. User Mode Linux will soon have the same capabilities as Xen in the virtualization arena -- like live migration, says Jeff Dike, author of User Mode Linux. Operating out of the Linux kernel port, UML enables the port to host multiple virtual operating systems.

Speaking with SearchOpenSource.com, Dike described the pros and cons of virtual machines versus virtual operating systems and offers some advice on whether to opt for UML, Xen or VMware.

SearchOpenSource.com: You mentioned that User Mode Linux differs from other virtualization technologies because it's more of a virtual operating system than a virtual machine. How does a virtual operating system compare with a virtual machine?

Jeff Dike: A virtual operating system has greater contact with the host operating system. This allows interactions between guest and host, which would be difficult or impossible with a virtual machine. For example, UML has two file systems [with somewhat different properties], which allow a host directory to be mounted as a UML file system.

Full Story.

In another interesting interview

In another interesting interview at SearchOpenSource.com:

There is a new open source software legal battle brewing. It concerns Red Hat Inc., JBoss, which is now a division of Red Hat, and a relatively unknown company called FireStar Software Inc. Boston intellectual property attorney Tom Carey argues that, for now, users might be better off taking a good look at proprietary software before jumping into open source, if only until the specifics of the case become better known.

Already, there have been conspiracy theories regarding Microsoft/FireStar collusion since Microsoft was a listed partner of FireStar in the past. Is FireStar getting legal assistance from Microsoft?

Carey: There is no evidence of that, but that point is really sort of intriguing, and may pop up in the discovery phase of the litigation. The fun part of the SCO case was that that company was publicly held and had to disclose many of the things it probably did not want to disclose during the course of that trial. With this trial, that kind of information is not going to be available.

That Interview.

When A Computer Is Ready for the Junk Pile

Windows 'Upgrade'

  • When A Computer Is Ready for the Junk Pile
    To that point, there was a report that a mail server failure in a large business office remained a mystery for two days until someone found an old Pentium II back in the corner of some obscure closet with a burned out power supply. It is reported that the Slackware/Debian/Red Hat machine had been plugging away as a mail server for a number of years, completely unattended. That’s feasible I suppose, but I further suppose that it’s a modern day parable about how open source can indeed, carry the day.
  • Microsoft draws flak for pushing Windows 10 on PC users
    With about a month left for many PC users to upgrade to Windows 10 at no charge, Microsoft is being criticized for its aggressive — some say too aggressive — campaign to get people to install the new operating system.
  • Microsoft forks out thousands over forced Windows 10 upgrade
    Microsoft has had to pay a Windows user in California US$10,000 over a forced upgrade to Windows 10, according to a report in the Seattle Times. The user, Teri Goldstein, runs a travel agency in Sausalito, a San Francisco Bay Area city in Marin County, California.
  • A lawsuit over an unwanted Windows 10 upgrade just cost Microsoft $10,000
    Microsoft recently paid a (very small) price for its Windows 10 upgrade tactics, and that was before they became increasingly aggressive.
  • Updategate: California woman awarded $10,000 for borked Windows 10 upgrade
    A CALIFORNIA woman has set a precedent after a court ruled that she was entitled to damages over the installation of Windows 10 on her machine. Teri Goldstein, a travel agent, testified that the new operating system had auto-downloaded, started to install, failed, and left her Windows 7 computer running painfully slowly and often unusable for days. "I had never heard of Windows 10," Goldstein told reporters. "Nobody ever asked me if I wanted to update."
  • Microsoft pays out $10,000 for automatic Windows 10 installation
    Company withdraws appeal leaving it liable for $10,000 compensation judgment after botched automatic upgrade of travel agent’s computer
  • Microsoft Pays Woman $10,000 Over Its Forced Windows 10 Upgrade
    As a result of a legal suit, Microsoft has paid a woman $10,000 over the forced Windows 10 upgrade.
  • 'I urge everyone to fight back' – woman wins $10k from Microsoft over Windows 10 misery
    A California woman has won $10,000 from Microsoft after a sneaky Windows 10 update wrecked the computer she used to run her business. Now she's urging everyone to follow suit and "fight back." Teri Goldstein – who manages a travel agency in Sausalito, just north of San Francisco – told The Register she landed the compensation by taking Microsoft to a small claims court. Rather than pursue a regular lawsuit, she chose the smaller court because it was better suited to sorting out consumer complaints. Crucially, it meant Microsoft couldn't send one of its top-gun lawyers – or any lawyer in fact: small claims courts are informal and attorneys are generally not allowed. Instead, Redmond-based Microsoft had to send a consumer complaints rep to argue its case.
