They haven't bothered to update for 5.4, and it's very crashy. You can get the libc.so from 5.3 and put it in its library path to help. Search on 'vmware glibc 5.4'. If you're willing to switch from Xen, you might also try out KVM. It's much easier to deal with than the VMWare tomcat/browser/browser-plugin monstrosity, especially if you use X. I've got a Win2K3 machine here in an old version of KVM (less optimized) and launching Firefox only briefly moved the CPU meter to 23%. IOW, it seems normal. -Bill -- Bill McGonigle, Owner BFC Computing, LLC http://bfccomputing.com/ Telephone: +1.603.448.4440 Email, IM, VOIP: bill at bfccomputing.com VCard: http://bfccomputing.com/vcard/bill.vcf Social networks: bill_mcgonigle/bill.mcgonigle
