Created attachment 412426 [details] serial console output showing the kernel boot and panic. Description of problem: When doing an initial boot of anaconda to start a RHEL 6 beta 1 install inside of KVM, the guest encounters a kernel panic early on which prevents installation of RHEL 6 beta 1. Version-Release number of selected component (if applicable): Host (x86_64): - RHEL 5.5 + errata - kernel-2.6.18-194.3.1.el5 - libvirt-0.6.3-33.el5 - kvm-83-164.el5 Guest (x86_64): - RHEL 6.0 beta 1 - kernel-2.6.32-21.el6 How reproducible: Every single boot attempt. Steps to Reproduce: 1. Boot guest with 512MB of RAM (tried up to 2GB) using local iso file (RHEL6.0-20100420.n.0-Server-x86_64-DVD1.iso) 2. Select the first option in the bootloader: "Install or Upgrade an Existing System" 3. Watch the kernel boot up and fail. Actual results: Kernel boots and shortly after encounters an oops and a kernel panic, preventing the install. Kernel panic - not syncing: Fatal exception Pid: 1, comm: init Tainted: G D 2.6.32-21.el6.x86_64 #1 Call Trace: [<ffffffff814c6284>] panic+0x78/0x137 [<ffffffff814ca23c>] oops_end+0xdc/0xf0 [<ffffffff81038543>] ? kvm_leave_lazy_mmu+0x63/0xa0 [<ffffffff81042272>] no_context+0xf2/0x260 [<ffffffff81038543>] ? kvm_leave_lazy_mmu+0x63/0xa0 [<ffffffff81042505>] __bad_area_nosemaphore+0x125/0x1e0 [<ffffffff8110dbe8>] ? __alloc_pages_nodemask+0xf8/0x6d0 [<ffffffff810425d3>] bad_area_nosemaphore+0x13/0x20 [<ffffffff814cbccf>] do_page_fault+0x2ef/0x3e0 [<ffffffff81038543>] ? kvm_leave_lazy_mmu+0x63/0xa0 [<ffffffff814c9595>] page_fault+0x25/0x30 [<ffffffff81038543>] ? kvm_leave_lazy_mmu+0x63/0xa0 [<ffffffff81136e8a>] move_page_tables+0x46a/0x610 [<ffffffff8116ae68>] setup_arg_pages+0x188/0x330 [<ffffffff811b4f4f>] load_elf_binary+0x4df/0x1b50 [<ffffffff8112af47>] ? follow_page+0x2f7/0x410 [<ffffffff8112af47>] ? follow_page+0x2f7/0x410 [<ffffffff8112ff4f>] ? __get_user_pages+0x10f/0x420 [<ffffffff811b236c>] ? load_misc_binary+0xac/0x3e0 [<ffffffff8121720e>] ? ima_iint_find_get+0x2e/0x40 [<ffffffff8116b63d>] search_binary_handler+0x11d/0x360 [<ffffffff8116c875>] do_execve+0x245/0x320 [<ffffffff8125780a>] ? strncpy_from_user+0x4a/0x90 [<ffffffff8101159a>] sys_execve+0x4a/0x80 [<ffffffff81014208>] kernel_execve+0x68/0xd0 [<ffffffff8100a223>] ? run_init_process+0x23/0x30 [<ffffffff8100a320>] init_post+0xf0/0x110 [<ffffffff818bc875>] kernel_init+0x2a3/0x2ae [<ffffffff8101418a>] child_rip+0xa/0x20 [<ffffffff818bc5d2>] ? kernel_init+0x0/0x2ae [<ffffffff81014180>] ? child_rip+0x0/0x20 Expected results: Kernel does not panic.

Created attachment 413144 [details] serial console of boot output from rhel 6 beta snap 1 Just tried with snap 1, which includes kernel-2.6.32-22.el6 and encountered the same issue which is preventing the install of RHEL 6 beta as a KVM guest running on a RHEL 5.5 host. Attaching capture of boot from serial console.
Can you test with 1G of guest RAM?
As originally posted, I already tried with up to 2GB for guest memory set and still this issue reproduces 100% of the time.
The patch on bz #574621 should fix this, marking as a duplicate. I don't know whether that patch is already part of an official update, apparently not. *** This bug has been marked as a duplicate of bug 574621 ***
